The Diamanti ATERNA® Oval is most similar to a round-brilliant cut and combines the round's sparkle with a flattering, elongated outline. It makes a good choice for someone who wants a unique shape but loves the fire and brilliance of a round diamond. Its design is even and perfectly symmetrical, with 58 facets to show off its brilliance.

Derived from one of the rarest minerals found in nature, Diamanti ATERNA is a revolutionary Lab Created Diamond Gem like nothing else you have ever laid eyes on. With incredible diamond brilliance, it captures even the slightest light source transforming it into an intense scintillation of fire and sparkle. With fiery dispersion spectacularly emitted by ATERNA, it rivals any natural gemstone for fire and brilliance.

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.
