Selenite

 

a mineral, a variety of gypsum with hairlike micro-crystals arranged in parallel fashion. Selenite is formed as a result of the filling of rock fissures, which accounts for the generally perpendicular arrangement of selenite fibers with respect to rock walls. It forms tightly bound mineral aggregates with a fiber length of up to 10–15 cm; the aggregates shimmer with an attractive silky luster in reflected light. The color of selenite depends on the admixture content and can be white, bluish white, yellow, or pink. Selenite is widely used as an ornamental material. Large selenite deposits are located in the Urals (Kungur, Sverdlovsk Oblast).
