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]
Fluorite on Quartz GeoKrazy Minerals
Description: Fluorite crystals, from Sturgeon Bay in Door County, Wisconsin. Field of view is about 4 cm. (Photo by W. Cordua) Fluorite often forms coarse cleavable masses or cubic crystals. It can take on a range of attractive colors, most often purple. Fluorite occurs in all types of hydrothermal deposits.
Mineral Specimen for Sale Fluorite and Quartz
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.
