gypsum, widespread sulfate mineral of terrific industrial worth, composed of hydrated calcium sulfate (CaSO4·2H2O). In nicely-developed crystals the mineral usually has been referred to as selenite. The fibrous substantial wide variety contains a silky lustre and is termed satin spar; it's translucent and opalescent and is particularly valued for ornaments and jewelry.
