Silicon Carbide, also known as carborundum, is an extremely rare mineral. Owing to the rarity of this mineral, it is often synthetic. It is commercially produced by heating carbon and quartz sand. Second to diamonds in hardness Silicon Carbide is used widely as an abrasive. In its natural form, Silicon Carbide is a charcoal-grey colour. These specimens are selected crystals before crushing and treated by bonding precious metals to the crystal for its iridescent effect.
