Purple And Orange Textures Of Fluorspar Stock Image

Fluorite (also called fluorspar) is the mineral form of calcium fluoride. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon.Pure fluorite is colourless and transparent, both in visible and ultraviolet light, but impurities usually make it a colorful mineral and the stone has ornamental and lapidary uses. Industrially, fluorite is used as a flux for smelting, and in the production of certain glasses and enamels. The purest grades of fluorite are a source of fluoride for hydrofluoric acid manufacture. Fluorite is useful in making apochromatic lenses, making it valuable, particularly in photographic optics.
