In the field of diamond jewelry, lab grown diamonds are increasingly used to replace natural diamonds in view of cheaper prices and richer colors.

They never lose their shine or color and are also cut and polished in the same way as natural diamonds, they have the same luster and fire as the natural diamonds.


Lab grown diamonds have the same chemical, physical, and optical characteristics as natural diamonds.
