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 che-mical 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. Check out the video in our Brand Store to watch the process in action!

At Carbon Atelier, we exclusively use laboratory made diamonds that we grow ourselves. This gives us the latitude to create jewelry that strike the perfect balance of beauty and value, delivering exceptional quality with the best cut, color and clarity... carat for carat.









CARAT - Because Size Matters

Carbon Atelier offers only genuine laboratory created diamonds set in fashionable jewelry silhouettes that every woman will love to wear or to receive.

Our specialty is larger-sized carat weights that are hard to find elsewhere. We make it easy to give in to your urge to splurge!

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 larger are 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.
