Selenite is a transparent, crystal form of the mineral gypsum, primarily composed of calcium sulfate dihydrate. It is known for its delicate, glass-like appearance and can be found in various colors, including clear, white, and orange. Selenite is often used in decorative items, such as lamps and sculptures, due to its aesthetic appeal. This mineral is commonly found in sedimentary environments, particularly in evaporite deposits. Selenite is also valued in the metaphysical community for its purported healing properties, believed to promote clarity and calmness. However, it is important to note that selenite is relatively soft and can be easily scratched or damaged.
