Fluorite Rainbow with Yellow Calcite Chalcopyrite or the formation of equallyFluorite is one of the most variable of all crystalline minerals, occurring in shades of blue, green, purple, red and many other colors corresponding to their physical makeup and conditions when the mineral was formed. The name fluorite comes from its use as a flux, or chemical cleaning agent, in iron smelting and other metallurgy. Pure fluorite is clear, but most specimens have vivid color due to various impurities and are often fluorescent. With a
