ATERNA Princess


The Diamanti ATERNA® Princess is a modern classic with clean square lines and beautiful sparkle. With 76 facets, this shape is the perfect choice if you prefer a square or rectangular outline but want the brilliance of a round.

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% 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.

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