The Diamanti ATERNA® Cushion possess 104 sparkling facets that shine and shimmer even in the lowest levels of light. Because these are relatively rare, this shape is for someone who wants something few people possess. The modern cushion shape is based on an antique cushion cut, which is a combination of round and square outline with a softened square or "pillow" shape.
Superbly Engineered in our state-of-the-art laboratories using our latest advanced patent rough processing, we achieve a colorless, pure, unique mix that gives the Aterna its diamond-like durability (9.50 Mohs) and incredible sparkle. The proprietary process for creating a single tailor-grown Aterna® Gem can take up to three months. 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 can handle the high stresses of being worn daily.
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.

DISCOVER ATERNA®
Eternal Elegance: Aterna's Timeless Beauty
Each individually hand-crafted ring is set with our incredible Diamanti Aterna. 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. Like a Diamond, Aterna is durable, tough and extremely resistant to scratching, and abrasion. With an impressive hardness of 9.5Mohs (a Diamond being 10Mohs), it is the second hardest Gem in the world and harder than a Sapphire, Ruby, and Emerald. This incredible durability makes it ideal for everyday wear.

ATERNA PASSES DIAMOND TESTING
Tests Positive For A Diamond
A diamond tester is a thermal conductivity meter that will detect the rate at which heat moves through stones and will tell you whether it is a diamond. Because of the high carbon content and similar heat signature, Aterna will test positive on most diamond testers.
Passes Fog Test
Diamonds effectively conduct heat and therefore disperse heat quickly. If you place a stone in front of your mouth and fog it like you would a mirror, if it stays fogged for a couple of seconds, it’s most likely not a diamond. Aterna, like a diamond, disperses the heat from your breath instantaneously and won't fog up.
Passes Transparency Test
A diamond refracts light so intensely that you cannot see through it. If you’re able to read the letters of the newspaper—even if the letters are a bit blurry, its most likely not a diamond. Aterna's facets will refract and bend the light so sharply that you wouldn't be able to see the print, thus passing the transparency test.
