Fluorite forms in a variety of colors and is transparent to translucent in clarity. The chemical composition of Fluorite is CaF2, (calcium & fluorine.) The variation in colors are due to trace amounts of other elements replacing the calcium during the crystalline formation. Fluorite is used in a variety of industrial purposes and the overwhelming percentage of Fluorite in the United States was mined in
