Lab Grown Diamond Stud Earrings – 18K White Gold 4-Prong Round Brilliant

A Pair Built Around Two Carefully Matched Round Brilliants

This pair of lab grown diamond stud earrings is set in solid 18K white gold, with each stone held in a classic four-prong basket. The diamonds are round brilliant cut and carefully matched at the bench for color, clarity, and proportion, so the two ears read as one set rather than two separate pieces.

The reference pair shown is approximately 6.2 mm per stone (around 1.7 to 2.0 ct total, depending on cut proportions). Within our earrings collection, this is the most classic position in the lineup: a solitaire stud designed to be worn alone, layered with a second piercing, or paired with hoops without competing for attention.

Four-Prong Basket, Threaded Post, Engineered for Daily Wear

The four-prong basket is the defining choice here. It sits the diamond up high enough for light to enter from the sides as well as the top, which is what produces the 360 degree sparkle you see when the wearer turns her head. The prongs are kept thin so they do not visually intrude on the stone, but each one is rounded and polished at the tip to avoid catching on hair or fabric over a day of wear.

The post is threaded and pairs with a screw back, which gives a higher retention level than friction push backs, particularly for stones at 1 ct and above where the weight starts to matter. The basket has an open underside, so the diamond can be cleaned through the back without removing the earring from the post. Standard reference dimension is 6.2 mm per stone; stone size scales with total carat weight (around 5.0 mm per stone at 1 ct total, around 6.5 mm at 2 ct total, around 8.0 mm at 4 ct total).

Solid 18K White Gold and IGI Certified Lab Diamonds

The basket, post, and screw back are all milled from solid 18K white gold (no plating, no fill), which is rhodium-finished at the final stage to give the cool, neutral white that complements diamond color without warm undertones. The two stones are lab grown diamonds, IGI graded in the F to G color, VS clarity, and Excellent cut range as standard, with higher grades available on request. Each stone is matched to its pair at the bench before setting.

• ◆ Each basket is hand-finished so the four prongs sit at equal height and equal tension on the stone
• ◆ Prongs are rounded and polished after setting, so they do not snag on hair or fabric
• ◆ Stones are matched pair by pair: same cut grade, same color tier, same measured diameter
• ◆ Final QC under 10x magnification covers prong seating, post alignment, and screw thread engagement
