Gypsum - Vasuki Mines Minerals

Gypsum (CaSO4.2H2O) is very similar to Anhydrite (CaSO4). The chemical difference is that gypsum contains two waters and anhydrite is without water. A massive fine-grained white or lightly tinted variety of gypsum, called alabaster, has been used for sculpture by many cultures. Gypsum also crystallizes as translucent crystals of selenite.
