    Most people don’t know that diamonds can be green too. It seems like the green color should be solely reserved for emeralds. Green diamonds are among the most wondrous works of nature, created in a unique process spanning over millions of years. They include some famous breathtaking diamonds in unique vivid shades.

    Superbly Engineered in our state-of-the-art laboratories using our latest advanced patent rough processing, we achieve a 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.

    ATERNA® Green is Made-to-Order. See Shipping/Delivery tab for completion estimates. Email us for possible available in-stock sizes.
