Fluorite has a wide variety of uses. The primary uses are in the metallurgical, ceramics, and chemical industries; however, optical, lapidary, and other uses are also important. Fluorspar, the name used for fluorite when it is sold as a bulk material or in processed form, is sold in three different grades (acid, ceramic, and metallurgical).

Fluorite , otherwise called calcium fluoride , is a non-silicate mineral with a calcium base. Due to impurities, fluorite also has a wide variety of colors from clear to shades of purple, blue, yellow or green. Some pieces of fluorite have a spectrum of colors and the ability to glow under ultraviolet lights.

Fluorite and amethyst quartz are sometimes confused simply because they both form purple translucent crystals, however the two are easily distinguished by their hardness (fluorite has a hardness of 4 and is easily scratched by a nail, while quartz at 7 is harder than a nail), shape (fluorite crystals are cubic, while quartz are hexagonal) and.

Fluorite typically glows a blue-violet color under shortwave and longwave light. Some specimens are known to glow a cream or white color. Many specimens do not fluoresce. Fluorescence in fluorite is thought to be caused by the presence of yttrium, europium, samarium [2] or organic material as activators.

Fluorite (also called fluorspar) is the mineral form of calcium fluoride, CaF 2. It belongs to the halide minerals. It crystallizes in isometric cubic habit, although octahedral and more complex isometric forms are not uncommon. The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 4 as fluorite. [6]
