A lab-grown diamond (sometimes called man-made or synthetic diamond) is the result of a technological process, as opposed to the geological process that creates natural diamonds. Lab-grown diamonds have essentially the same chemical composition, crystal structure, optical and physical properties of diamonds found in nature. Most lab-grown diamonds are categorized as either High-Pressure, High-Temperature (HPHT) or Chemical Vapor Deposition (CVD) diamonds, depending on the method of their production. Since HPHT and CVD diamonds grown in a laboratory are virtually identical to natural diamonds, differences only become clear when they are analyzed in a gem laboratory.


The timeless beauty of diamonds has enhanced the most gorgeous rings, earrings, bracelets and necklaces worn by royalty, great entrepreneurs and iconic film stars. The finest examples are famous in their own right. It is not surprising that most of us aspire to own a diamond for ourselves or to gift it to a loved one.

But a perfect stone may have imperfect origins. Even when you can be sure it has no connections with conflict or oppression, there can be serious concerns about mining and the environment. Many customers are now choosing grown diamonds in preference to their mined equivalent.


A certified la-grown diamond from EcoMoissanite provides superb quality, from an impeccable source. Our diamonds are manufactured in the United States, Europe and Asia. Once our diamonds have been lab-grown, they are faceted and polished by skilled cutters using traditional methods, in exactly the same way as mined diamonds.  Just like our moissanite gems, they are certified using a unique number, which is also inscribed around their griddle.
