Carbon Atelier’s large selection of jewelry is a must-see!

Fashion-conscious styles to collect compliments

If classic elegance is what she likes, it's here in this striking solitaire pendant necklace which features a beautiful lab-created white diamond in the square shaped princess cut, in a petite silhouette. The diamond is graded G-H color, and eye-clean Very Slightly Included (VS) clarity. The four V-shaped prong settings and bail are done in gleaming 14 Karat white gold, rose gold, or yellow gold, all suspended from a cable chain adjustable from 16" - 18", with a fancy criss-cross style decorative bail that allows the pendant to slide freely along the chain. A Lobster-claw style clasp provides security for all-day wear. This necklace is so versatile, pairing easily with evening wear but just as lovely with a summer dress or jeans and a sweater - and of course, diamonds are the perfect choice whether it is for a wedding, graduation, birthday or holiday, or just a way to tell her that you love and cherish her every day of the year. Don't miss this beautiful piece!

State-of-the-Art Stones

All of Carbon Atelier's 100% real lab-grown diamonds are created through the miracle of modern technology.

In our high-tech facility, an innovative process called chemical vapor deposition, or CVD, recreates conditions found in nature, using a hydrocarbon gas mixture to activate the carbon atoms in a tiny diamond seed. This causes the diamond crystal to grow, transforming the carbon vapor into real diamonds that are chemically, optically and physically identical to mined stones. Our premier-quality lab-created diamonds are so indistinguishable from natural diamond stones, even trained gemologists need special machinery to tell the difference.

Once the growing process is complete, each diamond is precision-cut and hand-polished to perfection, before being set by artisans with decades of experience in their craft.

CUT - For Sparkle & Reflection

All of Carbon Atelier's jewelry features stones with very good to excellent cut grades, lending exceptionally brilliant sparkle.

After being forged through the CVD process described above, our rough stones are expertly cut and polished by master artisans, for finished gems that dazzle, reflecting light with your every move.

COLOR - The Hue for You

Our designer jewelry features lab created diamonds in both colorless and near-colorless ranges.

When near-colorless and even faint yellow grade stones are set in yellow or rose gold, they can appear as white and bright as any colorless stones, since the color of the metal is reflected throughout the diamond.

CLARITY - Elements of Beauty

All of Carbon Atelier's lab-grown diamonds of 0.50ct or ensuring that you will always receive stones with clarity that is as good or better than the stated grade.

All of our Very Very Slight (VVS) and Very Slight (VS) clarity gems are eye-clean, giving them exceptional sparkle.
