Baguette Diamond Cross Necklace in 18K Gold

What Is a Baguette Diamond Cross Necklace?

A baguette diamond cross necklace is a cross pendant set with rectangular step-cut diamonds instead of round brilliants. This one is 18K solid gold, carries 3ct total across individually prong-set baguettes in a 15.5 x 29mm cross, and hangs on a fine-link chain adjustable from 38 to 48cm.

The long rectangular profile of each stone fills the arms of the cross with continuous coverage. Where round brilliant pendants produce scattered light points, baguette cuts produce broad flashes across the flat table of each stone. The result is a pendant that reads as structured and deliberate rather than decorative.

At 15.5 x 29mm, the cross sits at a scale that is visible at the neckline without dominating it. On a fine chain at 38 to 48cm, it falls at or just below the collarbone, easy to wear alone or layered over longer pieces. It sits in our diamond necklaces collection as the step-cut option, built for a buyer who wants defined geometry rather than scattered sparkle.

How Are the Baguette Diamonds Set?

Each baguette diamond in this cross is individually prong-set rather than channel or bezel mounted. Individual prong setting keeps each stone slightly raised, which allows light to enter from below the girdle and exit through the table in broad, flat reflections characteristic of step-cut diamonds. The cross arms are built from stones arranged in a line along the vertical and horizontal axes, with the center intersection occupied by the largest stone. The proportions of each stone are matched so the arms read as continuous rather than segmented.

The bail connecting the pendant to the chain is a small, integrated loop that keeps the cross centered and hanging level. The chain is a fine link style with a lobster clasp closure, proportioned to keep visual weight on the pendant rather than the chain itself. The overall pendant weight is approximately 5 grams in 18K gold, which sits comfortably against the chest without pulling.

What Gold and Diamonds Are Used?

The cross body and chain are produced in 18K solid gold (Au750), not plated or filled. White gold variants are rhodium-plated at our manufacturing facility before shipping to achieve the bright, neutral finish visible in the product image. Two diamond options are available for this design. Natural diamonds are graded at VS clarity and E color, sourced and confirmed at the production stage before casting begins. Lab grown diamonds of equivalent grade are available as an alternative, with a diamond test certificate covering the set for both options.

Baguette-cut stones require precise calibration during setting because their rectangular profile leaves less tolerance for seat adjustment than round stones. Our production team sets each stone under magnification, confirms seat depth and prong angle per stone, and verifies that the cross arms remain visually level across the finished piece.

• ◆ 18K solid gold cross body and chain, rhodium-plated on white gold variants before shipping
• ◆ Natural diamonds: VS clarity, E color, confirmed per stone before production begins
• ◆ Lab diamond option: equivalent grade, supplied with a diamond test certificate
• ◆ Baguette stones set individually under magnification, seat depth and prong angle confirmed per stone
• ◆ Final quality check confirms cross arm alignment and visual level across the full pendant face

What Can Be Adjusted Before Production?

This pendant is made to order at our manufacturing facility. The options below are the most common adjustments requested before production begins. If your requirement falls outside these, describe it in the inquiry form and the production team will confirm whether it can be accommodated.

• ◆ Stone type: natural diamonds (VS/E) or lab grown diamonds of equivalent grade. Natural diamonds carry GIA or IGI grading reports. Lab diamonds come with a diamond test certificate. Both options are available at the same setting and design standard.
• ◆ Gold color: white, yellow, or rose gold are all available. White gold is rhodium-plated before shipping. Yellow gold gives the baguette stones a warmer surround. Rose gold produces a softer contrast with the white diamonds.
• ◆ Gold karat: 14K is available as an alternative to 18K. 14K is slightly harder and holds rhodium plating longer on white gold variants. 18K carries more gold content and is the default for this design.
• ◆ Chain length: the standard range is 38 to 48cm. Lengths outside this range can be confirmed with the production team on inquiry. Chain style is a fine link, and alternative chain types may be available on request.
• ◆ Total carat weight: the 3ct total is set across the standard configuration. Scaling stone size up or down changes the pendant proportions. Confirm target carat weight and any size preference when sending your inquiry.
