Fluorite The mineral fluorite information and

Fluorite is a very popular mineral, and it naturally occurs in all colors of the spectrum. It is one of the most varied colored minerals in the mineral kingdom, and the colors may be very intense and almost electric. Pure Fluorite is colorless; the color variations are caused by various impurities. Some colors are deeply colored, and are especially pretty in large wellformed crystals, which Fluorite often forms.

Fluoride Wikipedia

Fluorine is estimated to be the 13thmost abundant element in the earth's crust and is widely dispersed in nature, entirely in the form of fluorides. The vast majority is held in mineral deposits, the most commercially important of which is fluorite (CaF 2). Natural weathering of these rocks, as well as human activity, releases fluorides into the biosphere through what is sometimes called the
