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 actually fluorescent and will glow when illuminated with an ultraviolet light source. Fluorite is mined for a variety of
