Selenite is a transparent, crystal form of the mineral gypsum. It is known for its delicate, fibrous structure 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 beautiful appearance and ability to reflect light. 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, including promoting mental clarity and emotional balance. However, it is important to note that these claims are not scientifically proven.
