What Is Selenite?
Selenite, chemically known as calcium sulfate dihydrate, has the formula CaSO4·2H2O. It is a colorless to white mineral, often presenting in a transparent form. This mineral is a variety of gypsum, which occurs naturally as calcium sulfate dihydrate. Among its various forms, selenite stands out as a colorless, transparent single crystal, emitting a bluish-white illumination reminiscent of moonlight.
Other forms of gypsum include snowflake gypsum (alabaster), characterized by its fine-grained texture, and fiber gypsum, known for its fibrous structure.
Uses of Selenite
Selenite is popularly used as a gemstone, valued for its perceived healing properties, which are believed to enhance insight and intuition. It is commonly fashioned into bracelets and other jewelry items, with prices varying widely based on quality and size. Due to its solubility in water, susceptibility to moisture, and low hardness, selenite requires careful handling.
Beyond its aesthetic uses, calcium sulfate, the primary component of selenite, has diverse applications in industries such as construction (in wall paints and cement), ceramics, pharmaceuticals, and food production. It is also used in coagulating tofu and as a desiccant.
