Most advice on choosing a wedding band for three stone engagement rings is about style: matching the metal, plain or pavé. This is written from the production floor and it is about geometry: what two side stones do to the space a band needs, and how a band is shaped to fit them.

The short version

What two side stones do to the space

A solitaire head is one stone wide. A three stone head is three stones wide, and the side stones sit lower and further out along the finger than the center. On this ring the oval is flanked by two trillions, triangular stones whose outer edges reach down toward the shank. A straight band slid up against the ring meets those side stones first. It cannot get closer, so it stands off the shank and leaves a visible gap between the two rings.

The gap is not only a look. It lets the two rings twist against each other through the day, and the parts that meet are the side stones. Two facts about diamond matter here. Diamond is the only common material that can scratch a diamond. And a trillion is at its thinnest at the corners, which is where a hard knock turns into a chip. A straight band set with diamonds, pressed against trillion corners every day, puts both risks in the same place.

How a fitted band is made

When we make the ring, the band is drawn around the ring’s own CAD model. The dip follows the outline of the head and the side stones, with a small clearance so the band does not grind on the setting, and it returns to full height where the shank is plain. The client sees both on the same rendering before anything is cast.

The model is not the last word. A cast and polished piece is never exactly the drawing: across our production a finished piece weighs about 90 percent of its model estimate, because filing and polishing take metal off. So after casting, the band is tried against the finished ring at the bench and the curve is adjusted before final polish. That fitting is the step that turns a band that nearly fits into one that sits flush.

A ring made elsewhere can still get a fitted band, but it has to be measured first, and the closer we can work to the ring itself, the closer the fit.

Why this band is plain and polished

The engagement ring already carries a lot: a colored center, two white side stones, and a shank made of two twisted strands. A plain polished band next to it gives the eye somewhere to rest, and it keeps gold, not stones, against the trillion corners.

Both rings are 14K, stamped Au585. 14K is a little harder than 18K, which suits two rings that will spend years touching, and the same design in 14K weighs about 90 percent of the 18K version. For a band that sits next to a solitaire instead, a diamond band such as our curved diamond wedding band works well.

Two things push back the other way

A curved band fits the ring it was made for, and only that ring. If the engagement ring is ever reset, or the center stone changed for a different shape, the band may stop fitting. A straight band does not care what it sits next to.

Worn alone, a curved band also looks like what it is: a band with a dip in it. Some people like that. Others want a wedding band that stands on its own and are happy to live with a small gap. A gap is not a defect, it is a choice, and on a ring with a high set head it may not appear at all.

Rings that sit flush also rub on each other, and over years they polish each other where they meet. Some couples have the two soldered together after the wedding. That stops the rubbing, but it turns a later resize into a two ring job, and some ring designs cannot be resized at all, as covered in rings that cannot be resized.

Ordering a ring and band together

• The center stone: shape, size and color, lab grown or natural diamond, or a colored gemstone
• Side stones: trillions like these, or pears, rounds or baguettes, each of which changes the curve the band needs
• Karat and color: 9K, 10K, 14K, 18K or 22K in yellow or rose gold, or platinum. White gold is rhodium plated, and the plating wears gradually with friction
• The band: plain or set with stones, and how far the stones should run
• Your ring size, and engraving for either ring, which is free

Our engagement rings and wedding bands can be made as a matched pair this way, including the radiant cut three stone ring with trillion side stones.

An order quoted from an existing design starts with a 30 percent deposit, which covers the design work and the production slot. The CAD rendering is free, materials are not ordered until you approve it, and the deposit is fully refundable before that approval.

Production usually takes 7 to 10 days after design details are confirmed. We ship by FedEx, DHL or UPS, and delivery usually takes 2 to 5 days, depending on destination and customs clearance.

Common questions

What wedding band goes with a three stone engagement ring?

A band curved to follow the head will sit flush. A straight band will usually stand off the ring because it meets the side stones first. Plain gold is the safer choice next to trillions or other pointed side stones.

Can you wear a straight wedding band with a three stone ring?

Yes, if you are happy with a gap between the two rings, or if the head sits high enough for the band to slide under the side stones. Check how far down the side stones reach before choosing.

Do I need a curved band for an oval three stone ring?

Usually, if you want the rings to sit together. An oval center with side stones spreads the head along the finger, and the side stones decide the curve more than the oval does.

Can a wedding band be made for a ring I already have?

Yes. The ring has to be measured first so the curve can be drawn around it, and the band is fitted against the ring before final polish.

Should the engagement ring and wedding band be soldered together?

It stops the two rings rubbing and twisting, which some people prefer. The cost is flexibility: resizing then involves both rings, and you can no longer wear one without the other.

About the Author and Review Process

Edwin Lin is the founder of Redora Jewels, a factory-direct fine jewelry manufacturer based in Shenzhen with on-site production. The ring and band in this article were photographed and filmed on our production floor, and the stamps, the karat weight rule and the fitting step come from our own production.

Redora Jewels has run as a manufacturing facility since 2011 and makes custom jewelry in solid gold and platinum, one piece at a time. If you have a three stone ring that needs a band, or want the two made together, start a project with Redora’s production team.

Most writing about matte rings compares the look. This is written from the production floor: what the finish physically is, at which step it goes on, and what happens to it after months on a hand.

The short version

What sandblasting does to the gold

Sandblasting is not a coating and it is not plating. A stream of fine abrasive hits the surface and leaves a field of tiny pits. A polished surface sends light back in one direction, which is where the mirror highlight comes from. The pitted surface scatters it. So the gold reads soft and even, a shade paler than the same alloy polished, with no bright streak running across it.

The karat does not change. We alloy 18K at 755 parts gold per thousand, a little above the 750 the stamp promises, and that alloy runs all the way through the band. The frost sits only on the outermost surface. Turn either band over and the inside is mirror polished, with the same Au750 stamp and the size, 56, which is the European size: 56 mm around the inside, about a US 7.5.

Two matte finishes, two names on our floor

Buyers often use matte, brushed and sandblasted as if they were one finish. At the bench they are separate jobs. Sandblasting is 打砂 or 喷砂 (pen sha, spraying sand). The brushed finish is 拉砂 (la sha, pulling sand): an abrasive wheel or pad is drawn across the surface in one direction, which leaves fine parallel lines. Our satin brushed 18K band is finished that way.

Where it sits in production

Sandblasting is one of the last steps, and the order matters. The band is cast, cleaned up and polished first, inside and out. The surfaces that must stay bright, the inside here, are then covered, and only the outer face goes into the blasting cabinet. If the blasting came first, the polishing wheel would take the frost straight back off.

Stones change the plan. Diamond is harder than any common blasting abrasive, so a diamond will not be marked by it. The metal around a pavé stone is a different matter. Each stone is held by small beads of gold that the setter cuts bright, and those bright cuts are part of what makes pavé sparkle. Blast them and they go dull. That is one practical reason this pair puts the two finishes on two bands instead of one: the pavé band stays bright, and the plain band takes the frost. Softer colored stones would be covered before any blasting. How the beads hold each stone is covered in how pavé setting works.

How a sandblasted gold ring wears

The frost is a field of tiny peaks. Every time the ring meets a desk edge, a door handle or the band next to it, the tips of those peaks are pressed flat, and a flat spot reflects light. So a sandblasted ring does not scratch the way a polished ring does. It slowly polishes.

• The high points go first. The crest of the wave, the outer edges, and the line where this band touches the pavé band will brighten before the rest.
• Fine scratches hide, deep ones do not. A hairline mark disappears into the frost. A gouge from a hard knock shows on any finish.
• It looks dirty sooner. The texture holds skin oil and soap film more than a polished surface, so the gold looks flat and dark before it looks worn. A soft brush and warm soapy water usually bring it back, as in cleaning gold jewelry at home.

How fast this happens depends on the hand. On a ring worn every day and never taken off, expect the high points to show within months, not years. On a ring worn on weekends, much slower.

Bringing the finish back

Because the texture is the metal itself, it can be redone. A worn band goes back into the cabinet with its inside covered and comes out frosted again. It takes very little gold off. The same works in both directions: a sandblasted band can be polished to a mirror if the owner changes their mind, and a polished band can be frosted.

This is the opposite of white gold, where the bright white surface is a rhodium plating that wears through and has to be put back. That case is covered in whether white gold needs to be replated. A sandblasted 18K yellow band has nothing to wear through.

Two things push back the other way

A matte ring does not stay the way it left us. The patchy stage, where the high points shine and the rest is frosted, is part of owning one. Some people like it as a record of wear. Anyone who wants the ring to look exactly as it did on the first day is better served by a polish, which hides nothing but is the easiest finish to restore.

Restoring is also less convenient. Almost every jeweler can polish a ring. Fewer keep a blasting cabinet, so a refinish may mean sending the ring back to whoever made it, or accepting a brushed finish in its place.

Why this pair splits the finishes

The two bands share one wave. The upper band follows the curve of the lower one, so they sit together without a gap and turn as one piece. A wave band only nests properly with the band it was drawn against, which is why a pair like this is designed and made together rather than matched later.

The contrast does the rest. Next to frost there is no mirror highlight competing with the diamonds, so the three rows of pavé read brighter than they would next to a polished band. For other shapes in our wedding bands, the wave diamond eternity ring puts the wave and the diamonds into a single band.

Ordering a sandblasted ring

• Most plain bands can take a sandblasted finish, on the whole outer face or on part of it, with the inside left polished
• Karat and color: 9K, 10K, 14K, 18K or 22K in yellow or rose gold, or platinum. In white gold the band is rhodium plated, as all our white gold is, and the plating wears gradually with friction
• Your ring size, and the band you want it to sit against if it is part of a pair
• Engraving inside, free, in the wording and font you choose

An order quoted from an existing design starts with a 30 percent deposit, which covers the design work and the production slot. The CAD rendering is free, materials are not ordered until you approve it, and the deposit is fully refundable before that approval.

Production usually takes 7 to 10 days after design details are confirmed. We ship by FedEx, DHL or UPS, and delivery usually takes 2 to 5 days, depending on destination and customs clearance.

Common questions

Is a sandblasted gold ring real gold?

Yes. Sandblasting changes the texture of the surface, not the metal. An 18K sandblasted band is 18K all the way through, and it is stamped the same as a polished one.

Does a sandblasted finish wear off?

It does not peel, because it is not a coating. With daily wear the high points slowly polish back toward a shine, starting with the edges and wherever the ring rubs against another ring.

Does matte gold scratch easily?

Fine scratches are harder to see on matte gold than on polished gold, because they blend into the frost. A deep scratch shows on either. Over time a matte ring gets shiny patches rather than a web of scratches.

What is the difference between sandblasted and brushed gold?

A brushed finish is made by pulling an abrasive wheel or pad across the gold in one direction, so it shows fine parallel lines. Sandblasting blows fine abrasive at the surface under air pressure, so the frost has no direction.

Can a sandblasted ring be polished later?

Yes. Polishing removes the frost and leaves a mirror finish. A polished ring can also be sandblasted later. Both are surface work on the same gold.

About the Author and Review Process

Edwin Lin is the founder of Redora Jewels, a factory-direct fine jewelry manufacturer based in Shenzhen with on-site production. The pair in this article was photographed and filmed on our production floor, and the stamps, the alloy figure and the finishing sequence come from our own production.

Redora Jewels has run as a manufacturing facility since 2011 and makes custom jewelry in solid gold and platinum, one piece at a time. If you want a band frosted, polished, or one of each, start a project with Redora’s production team.

Most answers to that question come from catalogues and size charts. This one comes from a single order on our production floor, with the model weights, the finished weights and the reason the band got heavier.

The short version

For a flat hinged bangle around 4 to 5 mm wide, those three numbers are a fair map of the range: 1.7 mm is the light end, 2.0 mm reads as solid, and 2.2 mm is a bangle you notice when you put it on. Width, karat, wrist size and engraving all move the answer, and the sections below show how.

What the image showed, and what it could not

An AI image is a mood board with perfect lighting. It has no scale. The caption under this one did carry real numbers: the karat, the gold color, a 4.8 mm width, a hinge and a twist lock, and a wrist size given in centimeters. That is more than most clients send. A bangle still needs more numbers than that before a model can be built.

• Thickness. Nothing in a picture says whether the band is 1.5 mm or 3 mm. Lighting and angle make both look plausible.
• The inner shape. A size in centimeters is a length. A hinged bangle is an oval, and the oval has to clear the hand when open and sit close when shut. Our designer set it at 53 by 63 mm.
• Where the hinge and the screw lock sit, and how many roundels fit between them without one landing on a seam.
• The lettering as a file. The image showed letters. Engraving needs outlines a machine can cut.

This matches what we see on most bangle inquiries. Clients usually give one or two parameters, we draw a first render from those, and the rest gets settled over a round or two of changes: bigger, smaller, wider, heavier. Nobody on the retail side sees that loop, because by the time a bangle reaches a display case every number in it was fixed long ago.

Three thicknesses before a gram of gold

The client first asked for a light bangle, and the first CAD went out at 1.7 mm with a model weight of about 20 g in 14K. A cast band could have kept that weight, but not the hinge and screw lock the client wanted. Those had to be machined, and the machined construction is heavier. We set out both options before production, and the client kept the screw lock and accepted the added weight and labor. The second CAD went out at 2.0 mm, about 24.5 g, and production ran at 2.2 mm.

The weights need one note, because they look backwards at first glance. The 2.0 mm model says 24.5 g, yet the 2.2 mm bangles came off the scale at 23.16 g and 23.51 g. A model weight is an estimate of the cast, not the finished piece. It does not subtract the metal removed when the band is engraved, filed and polished. Across our production, a finished piece weighs about 90 percent of its model estimate. On that rule the 2.0 mm bangle would have finished near 22 g, and the extra 0.2 mm added a little over a gram to each.

The two finished bangles are 0.35 g apart. They share one model, one size and one karat. Two pieces finished by hand rarely match to the gram, which is why our quotes work from the scale weight and not from the drawing.

So how thick should a bangle be

There is no single right number, but there is a right way to choose one. These are the things that moved it on this order, and that move it on most.

• Width and thickness work as a pair. On this design, 4.8 mm wide, each extra 0.1 mm of thickness added about 1.5 g to the model weight. The band also reads heavier from the side than from above.
• Karat changes the weight, not the look. The same design in 14K weighs about 90 percent of the 18K version. In 18K, this 2.2 mm bangle would come to roughly 26 g. That is an estimate from our karat rule, not a weighed piece.
• Engraving takes metal away from the surface. Every roundel is cut into the outer face, so the band has to stay solid enough under the letters. This pair is solid gold through the full section. An engraved surface counts as textured under our own rule for hollow and semi-hollow gold, so a design like this could go semi-hollow at most, never fully hollow.
• The number is final once it is made. A finished bangle cannot be thickened, and it cannot be resized either, which is covered in why some rings and bangles cannot be resized. Thickness and the inner oval are both settled at the CAD stage, which is the cheapest place to change your mind.

A practical way in: if you own a bangle whose weight you like, weigh it and measure its width and thickness, then send us those three numbers. That tells us more than any description of how heavy you want it to feel.

The letters were the harder part

The client sent the fonts as pictures, one sheet for each position. A classic serif capital for the roundels. A flowing script for the inside line. A monogram that joins A and R with a looping crossbar, shown in copper on black. A separate serif for a karat mark and a short number.

None of these existed as a font file we could cut at roundel size. So our designer redrew each one from the client’s images, matching the stroke weight, the serifs and the slant of the script, and sent the result back as a screen image to compare against the originals. Only after the client approved the lettering did the roundels go into the model. The roundels were then cut by CNC engraving from that approved drawing, so every A matches every other A in depth and outline, and the same for every R.

Engraving is free on everything we make, in the wording and the font you choose. The work that takes time is not the cutting. It is turning a picture of a font into an outline that holds its shape at a few millimeters tall on a curved band.

Two things push back the other way

Thicker is not automatically better. Gold is priced by the gram, so the move from 1.7 mm to 2.2 mm put close to 30 percent more gold into each bangle, and the price followed. For a pair, that difference doubles.

A thicker band also stands further off the wrist. On a flat profile, that height is the part that meets a desk edge, a laptop or a shirt cuff first. For someone who types all day, 2.0 mm may be the better everyday choice even if 2.2 mm looks better in a photo. This client put the hinge and screw lock first and accepted the weight that came with them. That is not the right call for everyone.

Both designs are now made to order with any initial: the engraved gold bangle with the letter A and the custom gold bangle with the letter R. Our other gold bracelets follow the same CAD first process.

What to send if you are starting from an AI image

• The image itself, and any notes that came with it
• Your wrist measurement, or the inner size of a bangle that fits you
• A width and a thickness if you know them, or the weight and size of a bangle you already like
• Karat and gold color: 9K, 10K, 14K, 18K or 22K, in yellow, white or rose, or platinum
• The engraving text, and the font as a file or as a clear image

A project that starts from an idea, a sketch or an AI image carries a $40 CAD design fee before modelling, with revisions included until you are happy with the rendering. If you go ahead, the fee is credited in full against the order and the normal 30 percent deposit follows. If you decide not to, the fee is not refunded, because the design work is done, and you keep the rendered images. The full sequence is set out in how the deposit and the CAD fee work.

Production usually takes 7 to 10 days after design details are confirmed. Personalized pieces may require additional layout time. We ship by FedEx, DHL or UPS, and delivery usually takes 2 to 5 days, depending on destination and customs clearance.

Common questions

How much does a gold bangle weigh?

It depends on width, thickness, inner size and karat, in that order of influence for most designs. A flat 14K bangle 4.8 mm wide and 2.2 mm thick, with a 53 by 63 mm inner oval and engraved roundels, weighs 23.2 to 23.5 g finished. The same design at 1.7 mm would come in under 20 g, made with a screw lock on both sides instead of a hinge.

Can a jeweler make a bangle from an AI image?

Yes, as a starting point. The image fixes the look. The numbers that make it wearable, thickness, inner shape, hinge position and the lettering as cuttable outlines, are fixed in CAD, usually over one or two rounds of changes.

Can a bangle be made thicker after it is finished?

No. A finished bangle cannot be thickened or resized. If the thickness is wrong, the bangle is remade, so the CAD stage is where to settle it.

Will the finished weight match the CAD?

Not exactly. A model weight is an estimate before engraving, filing and polishing. A finished piece usually weighs about 90 percent of it, and the final figure is the one on the scale.

Can I use my own font for the engraving?

Yes. Send the font file, or a clear image of the lettering if there is no file. We redraw it at the size it will be cut and send it back for approval. Engraving is free.

Most writing about low MOQs comes from plated brass, stainless steel and silver suppliers, where minimums of 20, 50 or 100 per style are normal and the reasons behind them are real. Solid gold made to order runs on different arithmetic. This is written from the production floor, a layer below the agents and retailers who usually answer these questions.

The short version

The full commercial terms for brands are on our OEM and private label manufacturing page. What follows is the reasoning behind them, and the parts a founder should plan for that no terms page covers.

Why most jewelry factories ask for 50 or 100 per style

Minimums are not arbitrary. In plated and silver fashion jewelry, production is organized around volume. A master model goes into a rubber mould, the mould is injected with wax many times over, the waxes are cast together, and the castings are plated in batches. Chain and components are bought in bulk. A factory set up that way needs volume on each style before the mould, the plating run and the material order pay for themselves.

So low MOQ means different things depending on who says it. Under a widely watched YouTube video on choosing a jewelry manufacturer, one of the most liked comments named minimum order quantity as the question the video left out, especially for a small label just starting. A manufacturer replying in the same thread described a hundred per design as their normal run, and twenty per design as their concession to small brands. On r/jewelers, someone answering a designer who wanted “reasonable MOQs for a smaller brand” asked whether small meant 5, 10, 20 or 60 pieces. It is the right question. Put it to every supplier, including us.

Branding is the second trigger. A commenter under another video on sourcing jewelry pointed out that asking for a logo on the product is what triggers the minimum, usually because the logo needs its own tooling. A small brand then chooses between no branding, a higher unit cost, or more stock than it wanted.

In solid gold, piece one and piece fifty cost nearly the same

Our cost per piece does not depend on a mould or a batch. Each piece is cast from the approved design, then filed, set and polished on its own by bench staff who are paid per piece. Gold is bought by the gram at the same price whether the order is one ring or fifty. There is no line setup for a larger run to spread out.

Two lines move, and only two. A new design needs CAD work once, so on a single piece that work sits on one unit. And on a larger total we will take less per piece. Everything else is fixed per piece. That is why a one piece minimum is not a loss leader here, and also why our volume price breaks are modest. The fiftieth piece costs us close to what the first one did.

From above, a low minimum looks like a favor a factory grants. From the bench, it is simply how the cost is built. That is the part an agent placing orders with someone else rarely sees.

What sets the price of an 18K piece with lab grown stones

We do not send a price list, because the price of a solid gold piece is mostly arithmetic on its weight. Gold is priced per gram against the daily benchmark, so a quote follows the gold price of the day it is written. For most pieces the result lands at about $500 to $5,000.

Founders who model their margins on spot price times weight usually come in low, because three things sit between the spot price and what the metal in a piece actually costs.

For a plain gold piece, gold is roughly 75 to 80% of our price and labor about 20%. Stones change that split, and lab grown stones change it far less than natural ones. A lab grown diamond costs us roughly 20% of a comparable natural stone, which is why our guide to lab grown diamonds treats them as a budget lever rather than a compromise. On a line built on 18K and lab grown stones, the finished gram weight is the number that decides your retail price. The full arithmetic is in our cost breakdown of a custom diamond ring.

So the most useful thing to ask any manufacturer is not the unit price. It is the finished weight in grams, written on the quote. A finished piece weighs about 90% of the figure in its CAD file, so also ask which of the two a quote is based on. Ours states finished weight, and says so when an early quote has to use the CAD figure.

Three levers lower the price without lowering the karat:

• Construction. Wide bangles, heavy chains and large hoops can be built hollow or semi-hollow in the same 18K alloy at a lower gram weight. It has to be disclosed with the real weight, and on slim or stone-set pieces it saves almost nothing. The limits are in what we can hollow and what we cannot.
• Setting style. Prong, pavé, channel and bezel settings cost about the same in labor. Invisible setting costs about 50% more, and it is also the setting most likely to cause problems on the bench.
• A second karat for a second tier. The same design in 14K finishes at about 90% of the 18K weight and carries less gold in every gram. If the brand needs a lower price tier, that is the cleanest way to build one without redesigning.

Existing designs and your own designs are two different deals

The founder asked about both, and they work differently.

Existing designs are already developed, so there is no CAD work to pay for at the start, and most can be made in 18K with lab grown stones and your mark. They are also public. They sit on our site, and other clients can order the same design. They work well for filling out a first collection or testing a price point.

Your own designs start with an NDA, signed before you send files. They are never shown in our catalogue, on our social channels or to other clients, and the CAD files are released to you on request, so you are not tied to us to reorder your own piece. The fear behind that question is real. Under the same video on choosing a manufacturer, the most liked comment was a designer’s fear of factories stealing designs.

Modified designs sit in between. An existing piece with a different stone, proportion or karat goes through a CAD revision before production. Most projects reach a final CAD in 1 to 2 revisions, and complex ones in 2 to 3.

On the catalogue: we send a PDF on request, and the current range is on the site under fine jewelry.

What private label covers, and what stays your job

Covered from the first piece:

• Your mark beside the fineness mark, 750 for 18K. It does not raise the minimum and carries no tooling charge.
• Your packaging and your documentation. Nothing carries the Redora name unless you ask for it.
• A gold and diamond test certificate with every order. You are welcome to have pieces independently assayed on arrival.
• Engraving, free across the range, with the font and the wording chosen by you.

Three things stay with the brand, and they are easier to plan before the first order than after it:

• Assay office hallmarks. Where hallmarking is compulsory, the UK for gold articles over 1 gram being the best known case, the hallmark is applied by an independent assay office, not by the manufacturer. Other European markets have their own rules on which marks must appear and who may apply them. Check with your national assay authority first, then send us exactly what has to be on the piece.
• What you promise about small stones. Center diamonds from 0.30 ct upward can come with an IGI report. Accent and pavé stones are not graded one by one, so do not promise your customers a report for every stone.
• Disclosure on white gold. If the line includes white gold, it is rhodium plated over solid white gold. The plating wears with friction, fastest on rings, and can be re-plated, and your customers need to be told. The intervals are in how often white gold needs replating.

How a first trade order usually looks

Trade orders rarely look like fifty of one item. A typical one is a single bangle style in two or three gold colors and several sizes, a few pieces of each. Because the minimum is per design rather than per color or size, that order needs no workaround.

Two habits make a first order more useful than its size suggests. Order one difficult piece first, not your easiest one: pavé, a hinge or fine prongs tell you far more about a factory than a plain band does. And ask to see your own order on a live video call from the production floor, which an agent placing orders elsewhere cannot easily arrange.

Our rework rate runs at 1 to 3%, and the most common cause is not a defect. It is the color of a natural stone reading differently once it is set against metal. Lab grown stones are more consistent in color from stone to stone, which helps a brand twice: fewer reworks on the first order, and reorders that match the pieces already sold. The rest of the vetting is in our seven checks for choosing a gold jewelry manufacturer, and what we inspect before dispatch is in the five checks before a piece ships.

Timing and money on the first order

A 30 percent deposit starts the project and covers the design work and the production slot. Materials are not ordered until you approve the CAD rendering, and the deposit is fully refundable until that approval. What it pays for at each step is set out in what a custom jewelry deposit pays for.

CAD renders take 1 to 3 days. Production takes 7 to 10 days for most pieces after design details are confirmed. Simpler designs may complete sooner, often within 5 days, and complex pieces can take up to 15. Finished pieces ship by FedEx, DHL or UPS, usually in 2 to 5 days depending on destination and customs clearance. If a launch date is fixed, give it to us at the quote stage, so we can say whether it is realistic before you pay anything.

Where a one piece minimum is the wrong fit

Two things push back the other way, and a founder should weigh both.

One piece is not the same as cheap. On a new design, the CAD work sits on that single unit. If the goal is to test a design, one is right. If the goal is the lowest unit price on a new design, a few pieces spread the CAD work better.

Volume does not buy steep discounts here. If the plan is hundreds of identical units at the lowest possible unit price, expect the price breaks on solid gold made to order to be modest, because the cost per piece barely falls with quantity. What moves on a large order is our margin, not our cost.

And if the price point needs gold vermeil or plated silver, we are the wrong supplier. Everything we make is solid gold or platinum.

Common questions

Is the one piece minimum per design or per order?

Per design, and in every karat. One order can hold a single piece of each of ten designs, in different gold colors and sizes. There is no annual volume commitment.

How many pieces should a first collection have?

There is no production reason to start larger than you can sell, so the size of a first collection here is a cash decision, not a factory constraint. The trade orders we see are often one or two styles in a few colors and sizes.

Will putting my logo on the pieces raise the MOQ?

No. Your mark is applied beside the 750 fineness mark from the first piece, with no tooling charge, and nothing carries our name unless you ask for it.

Can another brand buy the same design?

An existing design from our range, yes, because it is public. A design you bring to us, no. It is covered by an NDA signed before you send files, and the CAD files are yours on request.

Do you work with lab grown gemstones as well as lab grown diamonds?

Yes. Lab grown diamonds and lab grown colored stones such as sapphire, ruby and emerald are set the same way as their natural counterparts, in solid gold or platinum. In the US, the FTC Jewelry Guides treat it as deceptive to name a lab grown stone without a qualifier such as laboratory-grown or laboratory-created directly before it, so carry that wording through to your own listings.

Do you have a catalogue for 18K gold gemstone jewelry?

Yes, as a PDF on request, and the current range is on our site. Most designs in it can be quoted in 18K with lab grown stones.

Can you work from reference images instead of technical drawings?

Yes. A sketch or a reference image is enough to start, and the dimensions are fixed at the CAD stage. A bangle, for example, needs a wrist size, a width, a thickness and either the stone sizes or a total carat weight. Many clients settle those over one or two rounds of renders.

About the Author and Review Process

Edwin Lin is the founder of Redora Jewels, a factory-direct fine jewelry manufacturer based in Shenzhen with on-site production. The minimum order, the cost lines, the fineness, surcharge and loss figures and the rework rate in this article are the ones our production team works to. The inquiry that prompted it is described without details that would identify the founder who sent it.

Redora Jewels has run as a manufacturing facility since 2011. The commercial terms for brands, including CAD ownership, the NDA, sampling and the deposit, are set out on our OEM and private label manufacturing page. One design with the metal, the stones and the quantity you have in mind is enough for a broken down quote: start a project with Redora’s production team.

Most writing on bringing your own diamond comes from retailers. For a retailer the stone is usually the largest part of the sale, so an outside stone is a lost sale before it is a technical question. This is written from the bench, where the only question is the stone itself.

The short version

A setting is built to millimeters, not carats

The first thing we ask for is not the carat weight. Prongs are modeled to a diameter, a basket to a length and a width, and the height of a setting to the depth of the stone. Weight decides none of those directly.

Two round diamonds sold as 1.00 ct can differ in diameter by a few tenths of a millimeter, depending on how each was cut. A shallow stone spreads wider. A deep one carries more of its weight below the girdle and faces up smaller. A seat cut for one will not hold the other properly, which is why the CAD is drawn around your stone and not around a catalog figure.

The photographs here follow one ring across our bench: the 20.06 ct emerald cut from our 20 carat size comparison. Its report gives three numbers, 18.16 x 12.73 x 8.29 mm, and those three numbers built the frame above. The last one is the one buyers forget. Depth is the stone’s height from table to point, and it decides how far the ring has to stand off the finger.

Older cuts have different proportions from modern ones, so a stone out of an inherited ring is modeled as it is, not as the modern round its weight suggests.

What happens on the day the stone arrives

Nothing is cut, cast or set against a stone we have not looked at. When it arrives we check it and tell you what we see: the quality grade as we read it, and any chips, abrasions or worn edges it already carries. The next step waits until both of us agree on that record.

The record does two jobs. It answers the question buyers type most bluntly, which is whether a jeweler can swap a diamond. And it is the baseline any damage claim is measured against, which is what makes the promise further down something either side can check.

Our read of a grade is an opinion from the bench, not a laboratory report. Individual reports are rarely issued below roughly 0.30 ct, so most small stones arrive with no paperwork at all. For those, the arrival record is the only description of the stone that exists, which is the reason to make one before anything else happens.

Keep your own copy as well. Write down the report number, which IGI and GIA both let anyone look up on their websites, note the measurements, and photograph the stone. You see the finished piece in photographs and video before the balance is paid, and you can hold the stone in them against both records.

Where a stone actually gets hurt

A buyer on a Reddit engagement ring forum described a jeweler who declined to set their loose diamond and offered one of the store’s own instead, on the grounds that the store’s stones would not crack during setting. The buyer thought it sounded off, and was right to. A diamond does not become tougher because the person setting it also sold it.

What changes the risk is the individual stone. For a diamond, the moment of real stress is when prongs are pressed down onto it, or a bezel is pushed over its edge. It is not the casting. The metal is cast and cleaned first, and the stone is set afterward. Lab grown and natural diamonds are set the same way and take that pressure the same way.

Who pays if it breaks

It is common for a jeweler to ask a customer to sign a release before setting a stone they did not supply, so that any damage stays with the owner. We do it the other way round. If your stone is damaged while it is on our bench, we replace it with an equivalent stone or pay its agreed value.

We can offer that because of the arrival record. A stone that came in with a chip at the edge is recorded with that chip. A stone that came in clean is recorded clean. If a stone arrives with damage near its edge, you hear about it before anything is cut, and the setting is chosen with it in mind.

What setting your own diamond costs

The quote has the same lines as any piece we make, with the stone line taken out. You pay for the metal and for the work. There is no handling fee and no surcharge for the stone being yours.

The metal is bought by weight. Casting and polishing lose about 11 percent of what goes in, so a finished 10 g piece needs 11.1 g of alloy at the start. We alloy above the stamp, 18K at 755 parts per thousand gold and 14K at 595, and a per gram alloying surcharge sits on top of the gold price. Karat also changes the weight of the same design:

The work is priced per stone, not per carat. A solitaire is one stone to set. A halo around it can be twenty or more. Most setting styles cost the same per stone. Invisible setting runs about 50 percent more, and it is also the style most likely to give trouble on the bench.

So the useful way to compare quotes for a setting is in grams and in stone count, not in dollars alone. Ask for the finished weight at your size. The full split for a ring where we supply the stones is in our custom diamond ring cost breakdown.

If you are sending old gold as well

Some buyers send old gold with the stone: a broken chain, a ring that no longer fits, a single earring. We test its karat before anything is melted, and the gold it tests at goes against the new piece. You pay the difference.

Two details decide how far it goes. Old gold is counted at what it tests, not at what it is stamped. And melting is not gram for gram, because the new piece still loses about 11 percent in casting and polishing.

Three things push back the other way

Bringing your own lab grown diamond can save less than expected. Loose lab grown stones now cost little enough that, on a stone of a carat or two, the money saved by buying it yourself can be small next to the cost and effort of sending it across a border and having it checked. If you have not bought the stone yet, ask for the quote both ways: with your stone, and with one we source to the measurements the design needs. The material itself is covered on our lab grown diamonds page.

A stone that has lived in another ring has a history you cannot see yet. Wear on facet edges and chips under old prongs only show once the stone is out and under magnification. Setting does not cause that damage, but the arrival record will show it, and occasionally it changes what the stone can safely go into.

A colored stone can look different once it is set. Rework on our floor runs at 1 to 3 percent of pieces, and the most common reason is a natural colored stone that reads differently set than it did loose, because the metal behind it changes the color you see. If you are bringing a sapphire or an emerald, choose the metal color with that in mind. Yellow gold warms a stone and white gold cools it, and a pale stone shows the difference more than a saturated one.

The order of events, with your stone in it

Production takes 7 to 10 days for most pieces after design details are confirmed, as little as 5 for simple work and up to 15 for complex pieces. With your own stone, the clock also waits for the stone, because it cannot be set before it is here. The finished piece ships by FedEx, DHL or UPS, usually in 2 to 5 days depending on destination and customs clearance. Settle the ring size before the CAD is approved, since some rings cannot be resized once they are made. What happens to the deposit at each step is set out in what a custom jewelry deposit pays for.

The step that needs the most planning is not the setting. It is the journey. Carriers have their own rules on declared value and insurance for loose stones, and those rules sit with the sender. Talk to us before anything is posted, and send the stone once the brief and the quote are agreed.

Common questions

Can I bring my own diamond to a jeweler?

Many will set it and some will not, and the ones that will often ask you to sign a release first. We set stones we did not supply, record their condition on arrival, and cover them while they are on our bench.

Is there a setting fee for bringing your own diamond?

There is a setting fee, the same one that applies when we supply the stone, because the work is the same. There is no extra charge for the stone being yours.

How much does it cost to make a ring with your own diamond?

It is the metal plus the work. The metal depends on the finished weight and the karat, and the work depends mostly on how many stones are set. A photo of the design you want and the stone’s measurements are enough for a written quote, at no cost.

Can a jeweler swap my diamond?

It is the reason an arrival record matters. Ours notes the grade we read and the condition the stone came in, and both sides agree it before work starts. Keep your own copy with the report number and measurements, and compare the stone in the finished photographs before you pay the balance.

Can a diamond get damaged when it is being set?

It can happen, and for a diamond it is almost always at the moment prongs are closed. The risk sits in the individual stone: an existing chip at the edge, a thin girdle, or a sharp point left uncovered. If it happens on our bench, we replace the stone with an equivalent one or pay its agreed value.

Can you set a loose lab grown diamond I bought online?

Yes. Lab grown and natural diamonds are set the same way. Send the report or its measurements first, so the setting can be modeled before the stone travels.

My stone has no certificate. Can you still set it?

Yes. Most stones under roughly 0.30 ct never had one. The stone is measured and described in the arrival record instead, and that record is what we both work from.

Can you use my old gold as well?

Yes. It is tested for karat before it is melted, the gold it tests at is set against the new piece, and you pay the difference.

Edwin Lin is the founder of Redora Jewels, a factory-direct fine jewelry manufacturer based in Shenzhen with on-site production. The arrival check, the damage cover, the pricing lines, the fineness and loss figures and the rework rate in this article are the ones our production team works to. The photographs show a single ring on our bench, the 20.06 ct emerald cut engagement ring in 18K white gold, from empty frame to finished piece.

Redora Jewels has run as a manufacturing facility since 2011, making engagement rings and the rest of our custom jewelry to order. If you already have the stone, a photo of the design you want and the stone’s report or measurements are enough to begin: start a custom project with Redora’s production team.

Most writing on this question comes from the retail counter, where re-plating is a service on the menu. This is written from the bench where the plating goes on in the first place, and it covers the part the counter rarely shows: the metal underneath.

White gold is not bright white until the last step

The strip below is a real 18K white gold engagement ring photographed at six stages on our production floor. Look at the third frame. The bare basket is the raw alloy, and it is a pale warm color, not white. The bright finish in the final ring comes from rhodium, applied after setting and final polish.

The reason is arithmetic. We alloy 18K at 755 parts per thousand gold, slightly above the 750 the stamp requires, so three quarters of the metal is gold. The whitening metals pull that toward grey but not all the way. 14K, at 595 parts per thousand, carries less gold and starts a little less warm. The fineness figures are laid out in our custom diamond ring cost breakdown.

Rhodium is a hard, very white metal from the platinum group. It goes on as a thin electroplated layer, which is why it wears, and why US rules treat it as something a seller has to disclose. Under 16 CFR 23.7, failing to disclose a rhodium surface layer on a product described as precious metal is deceptive. Every white gold listing on our site states that it is rhodium plated for that reason.

Friction sets the interval, not the calendar

The plating does not age. It is worn away, and it goes fastest wherever the piece rubs against something harder than skin.

The first four rows follow the ranges jewelers who do this work commonly quote, for example in this re-plating guide from Robinson’s Jewelers. Only the ring figure is consistent from one jeweler to the next; the others vary. The earring row is our own experience, and it applies to pendants too: under normal wear, many of those pieces never need a second coat. Sweat and household chemicals shorten every row, and so does chlorine in pools and hot tubs, which attacks the alloy metals under the plating as well. Our note on wearing gold jewelry in the shower covers the chlorine side.

What yellowing is, and what it is not

When the rhodium thins, the warm base from frame three starts to show through, usually as a faint yellow cast on the palm side of a ring and along its edges. It is the same solid gold it always was. Nothing structural has changed, and the ring is exactly as strong as it was on the first day.

A warm cast is not, on its own, a sign that a ring was plated base metal. Solid white gold turns faintly yellow as it loses its rhodium precisely because it is mostly gold. If a ring shows it within a few months, the usual causes are hard daily use or a thin plating, and a karat stamp plus a jeweler’s acid or XRF test settles the metal question in minutes.

Re-plating is routine work at any jeweler with a plating tank: the piece is cleaned, the surface refreshed, and a new layer of rhodium goes on. It does not need to travel back to the maker.

Nickel is the question to ask before you buy

White gold alloys are whitened with other metals, and in ours that includes nickel. Our yellow and rose gold alloys contain nickel as well. We state it plainly because it is the single fact most worth knowing if your skin reacts to nickel, and because the common advice to switch to yellow gold does not hold with our alloys.

While the rhodium is intact, the skin touches rhodium rather than the alloy underneath. Once it wears through, the alloy is against the skin. That is one reason buyers sometimes describe wearing a white gold ring comfortably for years before a reaction appears.

We do not produce a palladium white gold. For a known nickel allergy the metal we recommend is platinum, which we make at 955 parts per thousand, which contains no nickel, and which needs no plating because it is white all the way through. Our brushed platinum wedding band is one example. If you are not sure nickel is the cause, a patch test from a dermatologist answers that before you commit to a metal.

Two things push back the other way

Platinum is not simply white gold without the maintenance. It is denser, so the same design carries more metal by weight, and its alloying surcharge is about 21 RMB per gram against 8 for 18K. It is also a poor metal to recover: if part of the plan is to melt a piece down into something new one day, karat gold gives far more of its value back.

Letting the plating wear is a legitimate choice. Some people prefer the softer, warmer tone of white gold without its rhodium, and a ring that has lost its plating has lost nothing else. Frame three above is roughly what that looks like.

The choice in one table

For most buyers of wedding bands and engagement rings, the choice between these comes down to color, budget and skin. The practical difference is that a white gold ring asks for a visit to a jeweler every year or two, and yellow gold and platinum do not.

Common questions

How often does white gold need to be replated?

On a ring worn every day, jewelers generally suggest every 12 to 18 months. Bracelets usually go around two years, and pendants two to three years or longer. Earrings and pendants worn normally often never need it. The practical trigger is appearance: re-plate when the palm side of the ring starts to look warmer than the top.

Why is my white gold ring turning yellow after a few months?

The rhodium on the palm side has worn thin and the alloy underneath is showing. White gold is mostly gold, so its base color is a pale yellow. Hard daily wear, sweat and chlorine speed it up. A re-plate restores the white finish.

Does white gold have nickel in it?

Many white gold alloys do, including ours. Some makers use palladium instead; we do not. If you react to nickel, ask any maker directly which whitening metal their alloy uses, and consider platinum.

Is white gold plated?

White gold is solid gold all the way through, with a thin rhodium layer on the surface. It is not gold plating over a base metal. The rhodium is a finish on top of solid gold, and a seller should disclose it.

Can white gold be worn without rhodium plating?

Yes. White gold without rhodium is structurally identical to plated white gold. It simply looks warmer, a pale greyish yellow rather than bright white, which is the color in frame three of the photo above.

Is 18K white gold whiter than 14K?

Under the rhodium, no. 18K carries more gold, so its base tone is slightly warmer, and the difference shows more once the plating wears. With fresh plating the two look the same.

What is the best metal for a nickel allergy?

At our end, platinum. It contains no nickel and needs no plating. Our yellow, rose and white gold alloys all contain nickel. A dermatologist’s patch test is the reliable way to confirm nickel is the cause before choosing a metal.

About the Author and Review Process

Edwin Lin is the founder of Redora Jewels, a factory-direct fine jewelry manufacturer based in Shenzhen with on-site production. He works directly with the production team on metal specification and finishing, including the rhodium step described here. The alloy, fineness and surcharge figures in this article are Redora’s own. The re-plating intervals are the ranges jewelers who do that work commonly quote, and the disclosure rule is cited from the US Code of Federal Regulations.

Redora Jewels has operated as a manufacturing facility since 2011, producing fine jewelry and the rest of our custom jewelry range to order. If you want to settle the metal before anything is cast, you can start a custom project with Redora’s production team.

Both answers are defensible, and the reason they differ is worth understanding before you order anything, because the question is settled in CAD months before anyone picks up a saw.

The question is about circumference, not skill

A ring size is a length of metal. One US size is about 0.81 mm of inner diameter, which works out to roughly 2.55 mm of circumference. That number is the whole problem in one line. Going down three sizes means taking about 7.6 mm out of the band and closing what is left. Going up means cutting the shank and soldering in a piece of the same alloy, or stretching the metal, which thins it.

Watch a public thread where someone posts a photo and asks whether their ring can be sized down, and the trade replies are rarely about skill. A working jeweler in one r/askjewelers thread from September 2026 described the job as “removing 2.5 millimeters of material per size then squeezing it”. Several commenters in the same thread said they were capable of doing it and would still decline. One of them put it plainly: the ring needs to be remade.

That is the distinction buyers rarely get told. A jeweler refusing a resize is often not telling you they cannot do it. They are telling you that what comes back will be worse than what you handed over.

What sits on the shank decides the answer

A resize happens at the bottom of the shank, directly opposite the center stone. Whether that is possible depends on one thing: how much plain metal is sitting there, and how far the stones come down the sides.

The middle row is where most disappointment lives, because it looks resizable. A pavé shank has plain metal at the bottom and stones only on the shoulders, so the photograph suggests there is room to work. What the photograph does not show is that squeezing a ring smaller changes the curve of the whole circle, including the part carrying stones. Shared bead settings hold two neighboring stones with the same piece of metal. Move that metal and both seats open.

This is not theoretical. In that same thread, a buyer with a split shank pavé ring described having it sized down from a 6 to a 4.25 and losing melee immediately, then five stones over eight years. The resize worked. It also started a slow leak.

The part nobody sees is how thin the shank already is

Under most stone set shoulders the metal is scooped out from below. It is a normal construction choice and there are two good reasons for it: the ring sits more comfortably against the finger, and the piece carries less gold for the same visual weight. Look at the underside of a commercial pavé ring and you will usually see the hollowed channel running under each row of stones.

The consequence only appears at resizing time. The area under the setting is already the thinnest part of the ring, and it is right beside the section being compressed. We cover the same logic in detail in our piece on how far a gold piece can be hollowed before the surface work suffers, and it applies here exactly: metal removed for one good reason is not available for a different job later.

Two numbers from our own production sit behind this. Casting and polishing lose about 11% of the metal that goes in, and a finished piece lands near 90% of what the CAD file predicts. A design that was already specified at the light end of its weight range has no margin left to give up at the bench.

Engraving sits exactly where the cut goes

Free custom engraving runs across our whole line, wording and font both open to the client, and the usual place for it is the inside of the shank at the bottom. That is the same few millimeters a resize removes.

In the same subreddit, a buyer had a hand engraved 18k band taken from a size 5 to a 4.5 by a local jeweler after being told the engraving would not be touched. It came back with letters missing from a word. Half a size is the smallest adjustment anyone makes, and it was enough.

If a piece carries engraving that matters, treat the size as fixed. There is no version of this where the text survives a shank cut untouched.

Bracelets, bangles and chains give three different answers

Rings dominate the question, but the same physics produces very different outcomes across the rest of the line, and clients are often surprised by which is which.

Chain bracelets and necklaces are the easy case. Length is built from repeating links, so adding or removing a few sections is straightforward work and the piece is unaffected either side of the change. If you are unsure of a length on a chain, that uncertainty costs you very little. The same is true across our gold necklaces and plain gold bracelets.

Tennis bracelets sit in the middle. They are also a line of links, so they can be shortened. The difference is that every link carries a stone, so shortening the bracelet removes diamonds along with length, and the clasp and the safety catch have to be repositioned afterwards. It is real work with a real cost, which is why wrist measurements come before CAD on our tennis bracelets rather than after.

Bangles are the hard case, harder than rings. A rigid bangle has to pass the widest part of the hand and then sit correctly on the wrist, so its internal dimension is doing two jobs at once and there is no margin in either. On a hinged bangle the hinge and the catch fix the geometry permanently. Once a bangle is finished, it is finished at that size. Thickness is fixed at the same stage, which is why we settle it in CAD: how thick a bangle should be, worked through on one order.

Earrings do not carry a fit dimension at all. Hoop diameter is a style decision, not a sizing one, so nothing here applies to them.

Why we remake rather than resize

Our position is narrow and we would rather state it up front than have a client run into it later. Once a ring or a bangle has been produced to a size, we do not alter it. If the size is wrong, we make the piece again.

The reasoning is that the circumference is not one specification among many, it is the spine that the rest of the design hangs off. Stone spacing, the arc the shoulders follow, the wall thickness under each seat, where the engraving falls: all of it was solved in CAD for one specific size. Cutting the finished piece means working against every one of those decisions at once.

It is also worth being honest about what a remake costs on our side, because the gold is the part people assume is lost and it is actually the part that survives. Metal is recoverable. Labor is not. Setting, finishing and QC all start from zero, casting and polishing take their 11% again, and the alloying surcharge is paid a second time: about 8 RMB per gram on 18k, 12 on 9k and 14k, and 21 on platinum. None of that is recovered by melting anything down.

Which is the real argument of this article. The cost of a wrong size is not a repair bill, it is a second production run, so the size deserves the same attention as the stone.

Getting the size right before anything is cast

Everything above is avoidable, and the checkpoints are all early.

Measure properly, twice, at a sensible hour. Our ring size chart and home measuring guide covers the paper strip method and the conversions. Fingers run smaller when cold and larger in heat, so a reading taken first thing on a January morning is not the size you want built.

Send both numbers if your knuckle is wider than the base of your finger. We can design around a two measurement gap. We cannot design around one number that turns out to be the wrong one of the two.

Say so if the size is actively changing. Pregnancy and significant weight change are the two cases where a full eternity design is the wrong choice regardless of budget, and where a plain or partly set shank earns its keep.

Ask for the fit aids to be built in rather than added later. Sizing beads, a sleeve or a euro shank all work far better designed into the CAD than soldered onto a finished ring, and they cost less that way too.

Use the CAD approval as the real deadline. Nothing is cast and no material is ordered until the rendering is approved, and the 30% deposit is fully refundable up to that point. We wrote about that boundary in what a custom jewelry deposit actually buys. Production runs 7 to 10 days after design details are confirmed, and the size is one of those details.

Common questions

How many sizes can a ring be sized down?

On a plain band, about two sizes is the usual comfortable range, and the metal is removed and the ends closed. With stones on the shoulders, one size is a more realistic ceiling. Beyond that the ring tends to come back out of round, which is what people are describing when they say a resized ring has visible points in it.

Can a full eternity ring be resized?

No. A full eternity band carries stones around the entire circumference, so there is nowhere to cut and nothing to add to. The only route to a different size is a new shank with every stone reset, which is a remake with extra steps.

Can you resize a pavé ring?

Usually about one size, and the stones nearest the work are the ones that pay for it. Shared bead settings hold neighboring stones in the same metal, so when the shank is compressed the seats open slightly. Some stones loosen straight away and others let go years later.

Can a bangle be resized?

Not on our side. A bangle has to clear the hand and then sit right on the wrist, and on a hinged design the hinge and catch lock the geometry. We take wrist measurements at the design stage and make the piece again if the size is wrong.

Can a tennis bracelet be resized?

Yes, by removing links, but each link carries a stone, so the bracelet loses diamonds along with length and the clasp and safety catch need repositioning. Getting the length right at CAD is cheaper than shortening it later.

Can a ring be resized more than once?

Each resize work hardens the metal around the join and leaves a little less material to work with. A plain band tolerates it better than a stone set one. On a piece you intend to keep for decades, plan on the size being set once.

What can I do if a ring is too big and cannot be resized?

Sizing beads soldered inside the shank, a horseshoe insert or a sleeve will all take up slack without cutting the ring, and a silicone adjuster is the zero risk version while you decide. None of them are elegant, and all of them are better than losing stones. If the gap is more than about two sizes, remaking the piece is usually the better answer.

Does a resize damage the engraving inside a ring?

If the engraving sits at the bottom of the shank, which is where it normally goes, yes. The cut is made through that section. Assume the text will be affected even on a half size adjustment.

He works directly with the production team on construction methods, metal specification, and the standards that decide how a piece holds up over years of wear.

Buying for a fixed date? Our guide to anniversary jewelry covers how far ahead to confirm a design, and which styles stay resizable.

The honest answer has three parts. Most deadlines we can meet. Some we could only meet by removing steps the buyer will never see. And a few requests are not slow at all, they are simply not producible as described.

Most writing about custom turnaround exists to reassure. This is written from the production floor, where a compressed schedule takes its cost out of specific places, in a predictable order.

What the production clock actually looks like

Before the exceptions, the normal range. These are bench days, not counting transit:

Shipping runs 2 to 5 days by FedEx, DHL, or UPS, depending on destination and customs clearance. One high jewelry commission sat far outside that range and ran close to two months, because of the number of large stones it carried. That is the exception rather than a hidden norm.

What moves inside the range is rarely the bench. It is the approval loop that happens before the bench starts, which is covered further down.

The order we turn down

The specific combination we decline is an extremely compressed deadline attached to a refund if the date slips.

Taken separately, neither is difficult. Tight dates are ordinary and we work to them constantly. Refund terms are ordinary too. Put together on a piece that is being made by hand, one at a time, they change what the schedule is for. The date stops being a target and becomes the only thing being promised.

At that point we would be agreeing to ship whatever exists on the date, inspected or not. We ship after a second inspection pass, and if a client tells us the date is fixed while the inspection is negotiable, we are being asked to make the quality the variable. Some clients say this directly: send it as soon as it is finished, do not stop to check it.

We would rather decline the order than take a deposit against a date we cannot hold honestly. A piece that arrives on time and comes apart in six months has not solved the client’s problem, it has moved it.

What a hurried piece loses, and in what order

This is the part almost no retailer knows, because it sits a layer below where retail operates. Time does not come out of a piece evenly. It comes out of the steps that are invisible on the day it arrives.

The third row is the one that matters. A setting that was hurried still holds on the day it ships, which is exactly the problem. It passes the only test the buyer is able to run at delivery, and fails the one that runs for the next ten years. Stone loss from a rushed setting almost never shows up while anyone is still thinking about the deadline.

The first two rows are quieter but they are what separates a piece that feels finished from one that merely looks finished in a photograph.

The inspection we will not skip

Every piece is checked a second time before it leaves the building. That pass looks for:

• Client specific requests. Whatever was written into the order, checked line by line against the finished piece.
• Closure movement. Clasps, hinges, and spring mechanisms opened and closed by hand rather than eyeballed.
• Hallmark clarity. The stamp legible, not merely present.
• Loose or missing stones. Counted and pressed, one at a time.
• Finished weight against specification. A finished piece lands at roughly 90% of the weight the CAD file reports, so the check is against the expected finished figure rather than the model.

Our rework rate runs between 1% and 3%. The most common cause is not a bench error at all. It is melee color matching across a batch, where the small stones are individually correct but do not read as one set under the same light. That gets caught on the second pass, and correcting it means going back to the setting stage. A compressed schedule has nowhere to put that work. The full list of what we check is in our note on quality control before a piece ships.

Specifications that fight each other

The second category we turn down has nothing to do with time. It is a piece specified thin and light, with a durability requirement attached to it.

Metal section is what carries load. A band, a bangle shank, or a claw has to have material in it to resist bending and to hold a stone under daily wear. When a design is pulled down to the lightest possible weight and the brief still says it must not deform, the two requirements are not in tension, they are mutually exclusive. There is no finishing step that puts strength back into a section that is not there.

What we do instead is quote the design at the section it actually needs, and show what that does to the weight and the price. If the answer is that the budget only supports the thinner version, that is a legitimate choice, and we will make it. What we will not do is make the thin version and agree that it will behave like the thick one. The refusal is not of the order. It is of the promise.

The request we cannot fill even when we want to

A third kind arrives regularly and deserves stating plainly, because it reads as evasion when it is not.

Clients sometimes ask for an IGI report on every stone in a pavé piece. Diamonds are graded individually and issued a report from roughly 0.30 ct per stone upward. Below that size the report does not exist to be supplied. A band carrying sixty melee stones carries sixty stones that were never graded one at a time, anywhere, by anyone.

So this is not a case of a manufacturer declining to hand something over. No manufacturer has it. What we can supply on those pieces is the gold fineness and a diamond test certificate covering the material. On a piece with a center stone above that threshold, the center stone’s own report comes with it, because that stone was graded on its own before it ever reached us.

Where speed is genuinely available

Two things push back the other way, and both are worth more than any promise we could make about working faster.

• A simple design really is five days. Plain bands, solid earrings, and pieces built from constructions we already run are fast because nothing about them is being solved for the first time.
• The approval loop is where the calendar actually goes. Bench time is fairly predictable. The variable is how many rounds it takes to settle the design.

That second point is the practical one. On a bangle we need the wrist measurement, the width, the thickness, and then either the total carat weight, the millimeter size per stone, or the stone count. Some clients send all of that with the first message and the render comes back once, correct. Others give one or two parameters, look at a render, adjust wider, adjust thicker, and look again. Both are normal and we work either way, but they produce very different calendars, and the difference sits with the client rather than with us.

If a date genuinely cannot move, the most useful thing to do is say so at the first message rather than at the render stage, and let us tell you which constructions fit it. That is a real conversation about custom jewelry and it usually ends with a piece that works, rather than with a refusal.

Common questions

How long does a custom ring take?

Five days for a simple design, 7 to 10 days for most, and up to 15 days for complex work, plus 2 to 5 days in transit. The design approval before that is the part that varies most.

Can you rush a custom engagement ring?

Often yes, if the construction is one we already run and the parameters are settled early. What we decline is a compressed date paired with a refund clause, because that arrangement asks us to ship without the second inspection. Most engagement rings that arrive with a real deadline get made, they just get made in a construction chosen to fit the time available.

What happens if I do not like the CAD render?

We adjust it. Some projects settle in one round and some take several, and neither is unusual. Changes made at the render stage cost nothing but time, which is the entire argument for not compressing that stage.

Can a ring be resized after it is made?

No. Rings and bangles are fixed once produced, and a size change means remaking the piece. Chain based pieces are different, because links can be added or removed easily, so necklaces and bracelets carry much less risk on sizing. This is the main reason we push for measurements to be confirmed before production on rings rather than after.

Why can I not get an IGI certificate for the small stones?

Individual grading starts at roughly 0.30 ct per stone. Melee below that size is not graded individually by any laboratory, so the report does not exist. The gold fineness and a diamond test certificate are what cover those stones.

Do you ever accept a rush order?

Regularly. The distinction is not urgency, it is whether the schedule leaves room for the piece to be checked before it ships. When it does, we take it.

Redora Jewels is a factory-direct custom fine jewelry manufacturer in Shenzhen, China. The facility has operated since 2011, producing in solid 14k and 18k gold with natural and lab grown diamonds. Details of the production sequence are on our manufacturing page. If you have a fixed date, tell us at the first message and we will tell you honestly whether it fits before anyone pays a deposit. You can start a custom project with us.

The honest answer has two halves. We can cast a clasp in 9k, and we do. But on the one component inside it that has to flex and return, we will still suggest 14k, and we say so before the order is confirmed rather than after.

Most writing about clasps is a list of types with pictures. This is written from the production floor, where the clasp is the part that comes back.

A gold bracelet clasp fails at the return, not at the gold

Read what people write when a clasp goes. Almost nobody describes a break. They describe something that stopped holding.

The sentence that sits underneath all of these is shorter and it is the reason any of this matters: that is how I lost my chain. A clasp does not fail into a repair. It fails into a loss, usually somewhere the wearer was not looking.

Hardness and springback are two different properties

9k gold is harder than 14k and 18k. That is true, and it is a real advantage on this kind of design, where the letter faces are flat and mirror polished and every scratch shows.

Springback is a separate property. A tongue works by being pushed out of shape each time the bracelet is opened, then coming back to exactly where it started. It has to do that thousands of times over the life of the piece. Harder alloys are not automatically better at it. The 9k alloys in our supply resist the first bend well and lose their return sooner, which is why a 9k clasp tends to ship working and stop closing securely a year or two later.

That gap between the two properties is the part almost no retailer knows, because it sits a layer below where retail operates. Nothing about it is visible in a product photo, and it does not show up in the first month of wear.

There is no 9k clasp on the shelf, and that is not the end of the sentence

We have written before that in the component supply we buy from, ready made chain and findings are produced in 14k and 18k, and 9k is not among the stock. That remains true. Clasps, jump rings, spring tongues and bails are bought in, and none of them come in 9k.

What that sentence does not cover is a clasp we cast ourselves. When a design is cast from scratch, the clasp can be part of the same pour as everything else, in whatever karat the piece is in. It stops being a purchasing question and becomes a production one.

Why this bracelet has a box clasp and not a lobster

The 9k letter link bracelet we produce is a run of flat letter charms, 8.5mm across, joined by jump rings. A stock lobster clasp is round in section and sits proud of that line. Put one on the end and the eye goes straight to it.

So the clasp on that piece is a flat box: a tongue that slides into a hollow bar, with a hinged catch that folds over the top as a second hold. It is cut to the same 8.5mm width as the letters and cast in the same 9k, which is only possible because we are casting the letters anyway.

The last row is a genuine cost. A fold-over catch is slower to open and most people need both hands. That trade is worth stating plainly, because it is the thing wearers notice first and the security is the thing they notice last.

What the finishing takes off

Casting a clasp instead of buying one is not a shortcut. On the LOVE YOU version of this bracelet the CAD file called for 14 grams. The finished piece weighed 10.74 grams at 17 centimetres. That is a loss of roughly 23 percent between the file and the box.

Our normal figure across most designs is closer to 10 percent. The difference here is surface. Flat faces have nowhere to hide a casting texture, so every letter and the clasp bar are filed down and then polished until they read as one continuous mirror, and all of that metal comes off. On a design with curves and stones, far less does.

That number is one piece, one length, one letter count. It is not a specification. Change the letters or the length and it moves.

Two things push back the other way

The case against 9k on a moving part is not the whole picture.

The first is that the hardness is genuinely useful here. A clasp bar on a bracelet takes more contact against desks and sleeves than almost any other part of the piece, and 9k holds that polished face longer than 18k does.

The second is the geometry. A weakened tongue inside a box clasp is a different situation from a weakened lobster spring, because the fold-over catch is a mechanically separate hold. It does not rely on springback at all. The failure that costs people their bracelets is a single spring quietly giving up, and this design does not have a single spring.

There is no number for how many times a clasp can be bent

This is the question people actually ask, usually phrased as how many times a clasp can be bent back before it needs replacing. There is no honest number, and anyone who gives one is guessing.

What decides it is not the count. It is how far past its shape the part travels each time. A tongue flexed slightly and released returns almost indefinitely. The same tongue forced open with pliers to make it grip again has been taken past its elastic range once, and from then on it is working from a new shape that is closer to failure. That is why the pliers fix works for a few weeks and then does not.

The practical version: a clasp that has already been bent back to fix it is on its second life, whatever the karat.

What we put where

On a made to order piece these are separate decisions, so they get made separately.

Nothing on that list is a rule about a gold bracelet clasp in general. It is how we split the decision when a piece is made to order and the components are ours to choose. A 14k tongue inside a 9k clasp is not visible once the piece is assembled. It is the one place we will quietly disagree with a request to keep everything to a single karat, and the reason is that we would rather the bracelet still close in five years than be able to say it is 9k throughout.

Before ordering

Three things are worth settling before a made to order bracelet goes into production, and none of them can be changed afterwards without remaking parts.

Wrist measurement first, because a letter link bracelet is cut to a length rather than adjusted to one. Clasp type second, since a flat box and a lobster suit different link shapes and different hands. Karat on the moving part third, which is the decision this article exists to make easier.

The rest of our wrist pieces sit under bracelets, and if the design is not one of ours yet, send the details through start a custom piece and we will tell you what the clasp needs to be before anything is quoted.

The honest answer has three parts. On large pieces hollowing works and it saves a lot of gold. On small pieces it saves almost nothing. And on anything carrying texture or stones there is a ceiling on how hollow we can go, which is the part almost nobody outside a production floor knows about.

Most writing about hollow gold is a warning: it dents, it cannot be fixed, avoid it. That is not what we see at the bench. Hollow is a tool we use deliberately, and the real limit is not durability. It is surface work.

Hollow does not mean the whole piece is empty

This is the first thing worth correcting. A hollow piece is not a shell throughout. Only the body is hollow. Every part that carries load or moves is still solid metal.

On a hollow chain the tube is hollow and the clasp is solid. On a hollow bangle the band is hollow and the hinge and catch are solid. On a hoop earring the curve of the hoop can be hollow while the hinge, the post, and the latch stay solid.

That split is the reason hollow pieces can be repaired at all. The parts that break are almost always the parts we never hollowed.

Where hollowing saves, and where it saves almost nothing

What you are buying in gold is weight, and weight follows volume. A hollow tube removes volume from the middle of a section, so the saving scales with how thick the piece is to begin with.

The Sofia hoop we produce is a useful reference because it sits at the small end. It is 15.46 mm across the outside and 4.46 mm at its widest point.

Under half the gold for the same outside dimensions, on a hoop that is only 15.46 mm across. On a piece three or four times that size the ratio gets better still, which is why hollowing is normal on wide cuffs and thick chains and rare on anything small. Below a certain section there is not enough wall left to work with, and the labor to form and close a very thin tube costs more than the gold it saves.

Two other numbers sit behind any quote we give. Casting and polishing lose about 11% of the metal that goes in, and a finished piece lands near 90% of what the CAD file predicts. Those apply to solid and hollow alike, but they matter more on hollow work because the margins are thinner.

The parts we never hollow

Clasps, hinges, latches, posts, jump rings, and anything that opens and closes repeatedly stay solid. So does any point where the piece takes a pull, such as where a chain meets a clasp or where a pendant hangs from a bail.

This is not a Redora policy so much as how the trade works, and it is worth knowing because it changes what a hollow piece actually is. A hollow chain is a solid clasp joined to a hollow tube. A hollow hoop is a solid hinge and latch joined to a hollow curve.

Texture and stones set the ceiling

Here is the part that decides most of our answers, and the reason the Sofia hoop is solid rather than hollow.

Anything cut into the surface needs metal depth to be cut into. The Sofia carries angled ribs around the full circumference of the hoop. Those ribs are formed in the gold itself, which means the wall has to be thick enough to hold the full depth of every ridge and still leave structure underneath. The same applies to stones: a setting needs enough metal below the seat to hold a stone properly, and that metal has to come from somewhere.

So the options are not simply hollow or solid:

Semi hollow means a cavity smaller than a full tube, with enough wall left for the surface work. It still saves gold, just less of it. We do not publish a minimum wall thickness because it changes with the depth of the texture, the size of the stones, and the diameter of the piece, and a number quoted out of context would be wrong more often than it was right.

The practical consequence for a buyer is simple. A big plain gold hoop can be hollow and will look identical to a solid one. A hoop with ribs cut around it, or with a row of stones set into the face, cannot be hollowed to the same degree, and a seller offering one at a fully hollow price is either selling something thinner than it looks or has shallower texture than the photograph suggests. This sits a layer below where retail operates, which is why the question rarely comes up before a piece is bought.

What can be repaired, and what leaves a mark

A retail jeweler commenting under a jewelry video wrote that he will never sell hollow chains because “It broke again” always comes back to his counter. That is a real experience, and it is worth taking seriously. It also describes a sales problem more precisely than it describes a metal problem.

Break it into two kinds of damage and the picture is clearer.

Damage we can repair properly. A snapped link, a failed solder joint, a worn jump ring, a loose clasp, a hinge that no longer holds tension. These are all solid metal at the point of failure, and repairing them is ordinary bench work on hollow and solid pieces alike.

Damage that leaves a trace. A dent or a crushed section in a thin wall. Repairing that means pushing the metal back out rather than adding metal in, and metal that has been stretched once does not return to exactly where it started. On a plain polished surface the result is usually invisible after refinishing. On a textured surface some of the pattern is lost across the repaired area, because the ribs sitting on that wall get flattened along with it.

So the honest framing is not that hollow pieces break and solid ones do not. Plenty of people wear hollow gold daily for years without trouble. The difference is that a solid piece has more material to absorb a knock, and that a dent in a textured hollow piece is the one failure mode where the repair does not fully undo the damage.

On a hinged hoop the weak point is not the wall

Worth separating out, because it applies whether the hoop is hollow or solid. On hinged hoops the part that fails first is the hinge, not the body. It is the only component that moves every time the earring is put on, and it is small.

We fit and test the hinge and the latch after the stones are set rather than before, and closing tension is checked by hand on every pair. It is a small step, and it addresses the failure that actually happens rather than the one buyers usually ask about.

How we answer the question now

When a client asks whether we can hollow a design, we work through it in this order: how large is the piece, what is on the surface, and where does it take load. Large and plain gets hollowed. Small gains little. Textured or stone set gets semi hollow at most. Load bearing parts stay solid regardless.

Across our earrings and the rest of our fine jewelry range the same logic applies, and we will quote a design both ways so the trade off is visible before anything is cut.

Common questions

Is hollow gold real gold?

Yes. Hollow refers to the shape of the metal, not its purity. A hollow 18k piece is the same alloy as a solid 18k piece. We run 18k at 755 parts per thousand against a 750 minimum, hollow or not.

Can hollow gold jewelry be repaired?

Most of the time, yes. Clasps, hinges, solder joints, and snapped links are solid metal and repair normally. A dent in a thin wall can be pushed back out, but if the surface carries texture, some of that texture will be lost across the repaired area.

How much lighter is hollow gold?

On the small hoop above, about 15 g solid against 6 to 7 g hollow for a pair, so a little under half the gold for the same outside dimensions. On larger and thicker pieces the proportion improves. On very small pieces it is not worth doing.

Can a textured hoop be hollow?

Semi hollow at most. The ribs are cut into the gold, so the wall has to carry the full depth of the pattern and still hold its shape. A fully hollow version of a heavily ribbed hoop is not something we would produce. The same trade off decides whether a ring shank can be cut later, which we cover in rings that cannot be resized.

Should I choose hollow or solid?

For hollow gold hoop earrings the answer turns on size and surface. Hollow is a reasonable choice on a large plain piece where the alternative is not buying it at all, which is the situation it exists for. Solid is the better choice on anything small, anything textured, and anything you expect to keep for decades. If budget is the constraint, dropping the karat or the dimensions is often a better lever than hollowing a small piece.
