Selenite is a calcium sulfate mineral that is the crystallized transparent variety of Gypsum. Satin Spar is the silky and fibrous variety of Gypsum that is abundant and commonly mislabeled as Selenite. Both of these can be found crystallized in the form of masses, acicular, granular, tabular, and prismatic shards. It was first discovered in 1747 by J.G. Wallerius and named after the Greek word meaning “moon” in reference to its blue and pale colors. Selenite is extremely abundant and can be found in nearly every country in the world. Some of the most abundant deposits on record are sourced from Morocco, Australia, Madagascar, Mexico, Brazil, and the United States. Gypsum occurs on every continent in the world and is the most abundant of all sulfate minerals. In the United States, Utah contains some of the most dazzling specimens known to the world.
