Gypsum

Gypsum is a soft sulfate mineral composed of calcium sulfate with the chemical formula CaSO4·2H2O. This mineral forms as an evaporite mineral and as a hydration product of anhydrite, and serves as reference for the hardness value of 2 on the Mohs scale. 

Selenite, desert rose, and Gypsum flower are all varieties of this same mineral and all show a crystalline structure. These "crystalline" varieties of Gypsum are sometimes grouped together and called Selenite. 

Large Selenite "sheets" can be found in Utah, whereas Selenite "blades" are found in Mexico, the most well-known location being the "Cave of the Crystals" in the state of Chihuahua. Gypsum is a relatively common mineral, and may be found throughout the world. Read More...
