ATERNA® Black are Fancy Black opaque diamond gems in the highest quality. Aterna Black stones don’t shine in the traditional sense. Black diamonds actually absorb light instead of reflecting it, meaning their beauty comes from their surface which is polished like marble.

The ATERNA® is a Lab Created Colored Diamond Gem like nothing else you have ever laid eyes on. Superbly Engineered in our state-of-the-art laboratories, our scientists prepare a specialized proprietary blend comprised of Pure Carbon, Pure Silicon and Pure Elements making it the second hardest Gem in the world at 9.5 hardness - only 2nd to a diamond at 10 Mohs hardness. Because of the high carbon content, it will test positive for a diamond on most diamond testers and pass the fog and transparency test. Like a diamond, it has excellent durability and can handle the high stresses of being worn daily. We use the latest advanced rough processing to achieve a colored pure poly-type giving the ATERNA exquisite intense color profiles.

Each ATERNA is hand-faceted and cut by hand by our master diamond cutters to Ideal/Excellent proportions, guaranteeing the highest quality. Without exception, these features clearly make the ATERNA the most advanced and affordable genuine diamond quality stone in the marketplace today.

ATERNA® Black is Made-to-Order. See Shipping/Delivery tab for completion estimates. Email us for possible available in-stock sizes.
