The 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.

Exceptionally Durable- Aterna® gems are superbly Engineered with a specialized proprietary blend giving the Aterna 9.5 Mohs hardness. ( only 2nd to a diamond at 10Mohs.)
Colorless D/E - The less color in a diamond, the more valuable it is. Aterna® stones are exclusively created to the top colorless grades.
Color Options - Aterna® is available in vibrant blue, pink, green or black hues making them a unique and eye-catching choice for any jewelry piece.
Aterna® offers several advantages over traditional diamonds. They boast exceptional color and cut, often surpassing the brilliance and fire of natural diamonds. Aterna is a more sustainable choice, as it avoids the environmental impact of mining. Additionally, they are more affordable, providing stunning beauty and quality at a fraction of the cost of natural diamonds.
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.
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.
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.
