Superbly Engineered in our state-of-the-art laboratories, our scientists prepare a specialized blend comprised of 50% Pure Carbon and 50% Pure SIC 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 poly-type 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.

Additional photos showcase the ATERNA Radiant in a customized Distinction ring.

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.
