    The Diamanti ATERNA® Marquise cut features a unique eye-like shape that gives them one of the largest surface areas of any diamond shape. This diamond shape features a total of 58 facets, featuring 33 on the crown and 25 on the pavilion. Known for its long and narrow pointed shape, the marquise-cut is essentially a modified brilliant diamond and, as a result, appears larger than it actually is.

    The marquise cut enchants with its exquisite elongated shape and gracefully pointed ends, resembling a delicate boat sail or a shimmering droplet of light. This cut's elegant symmetry and elongation create a captivating effect, enhancing the diamond's inherent brilliance and giving it a regal and timeless beauty that is both striking and sophisticated.

    Derived from one of the rarest minerals found in nature, Diamanti ATERNA is a revolutionary Lab Created Diamond Gem like nothing else you have ever laid eyes on. With incredible diamond brilliance, it captures even the slightest light source transforming it into an intense scintillation of fire and sparkle. With fiery dispersion spectacularly emitted by ATERNA, it rivals any natural gemstone for fire and brilliance.

    Superbly Engineered in our state-of-the-art laboratories, our scientists prepare a specialized blend 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 an exquisite D/E color profile.

    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.
