Superbly Engineered in our state-of-the-art laboratories, our scientists prepare a specialized proprietary blend comprised of Pure Carbon, Pure Silicon and 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 colorless pure polytype giving the ATERNA exquisite E/F and G/H color profiles.
Each ATERNA is hand-faceted and cut by hand by our master diamond cutters to Ideal/Excellent proportions, guaranteeing the highest light reflection entering the stone. Without exception, these features clearly make the Aterna the most advanced and genuine diamond quality stone in the marketplace today.
