ATERNA Cushion


The Aterna is a Lab created gemstone like nothing else you have ever laid eyes on. More rare and brilliant than a diamond it captures even the slightest light source transforming it into an intense scintillation of fire and sparkle.

Superbly Engineered in our state-of-the-art laboratories, our scientists prepare a specialized blend comprised of 50% Pure Carbon and 50% SIC that enhances the Aterna's core for diamond like durability (9.5 Mohs hardness - diamond being 10) and lifetime luster. 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.

To add the Aterna to any product with the equivalent center stone size, email us at service@quorri.com for pricing and availability.
