Lab Grown Diamonds
A lab-created diamond is “grown” inside a lab using cutting-edge technology that replicates the natural diamond growing process. The result is a man-made diamond that is chemically, physically, and optically the same as those grown beneath the Earth’s surface.

Luster
The manner in which light interacts with the surface of a gemstone is known as its “Luster”. This property of a gemstone is more of an observation used for comparative purposes than it is a scientific means of comparing. Several different factors play into the luster grading of a gemstone, which in its simplest form, just describes how light reflects on the gemstone surface. How well light reflects on the surface of the gemstone is dependent on other properties of the gemstones, such as its Refractive Index, its Hardness, and its level of polish.
