Moissantie Silcon Carbide Small

A high concentration of iron impurities cause this mineral to appear black and opaque. The surface displays bright variations of iridescent blue, purple and gold colours. It is almost as hard as diamond and is used as an abrasive and in ceramics.

While naturally occurring Moissanite is extremely rare, this man-made version is equally as beautiful. Also known as carborundum, this form of silicon carbide, is formed by crystallization of the natural silicon carbide.
