Elegant Gypsum Specimen

Gypsum is the mineral calcium sulfate dihydrate, CaSO4 * 2 H2O, a hydrous evaporite mineral. This crystal was harvested in California. It has lovely growth striations and an interesting shape. Gypsum is used in the manufacture of sheetrock or wall board, paper, glass, and ceramics.

Selenite is a very clean, translucent crystalline variety of gypsum, while alabaster is a massive variety of the same mineral.
