Fluorite, Rainbow

Fluorite is the mineral form of calcium fluoride, of the Halide family & has a hardness of 4 on the Mohs scale.  The name comes from Latin, meaning “to flow”, because fluorite is used as a flux agent in smelting. First written about in 1530, in 1852 it gave its name to the term Fluorescence & later to the element Fluorine.  Many types of fluorite glow under ultraviolet light, & some also exhibit thermoluminescence. Pure fluorine is clear, but impurities give it many different colors. It is used as lenses in telescopes & microscopes, as the main component in hydrofluoric acid manufacture & lapidary uses. Dubbed “The most colorful mineral in the world” Fluorite comes in all colors including white, clear & black.  Rainbow Fluorite is usually a mix of purple and green, but can be any combination of colors.  It is found often in massive form and carved into shapes and for display and jewelry.
