Fluorite is a group III mineral (halides) that, according to Strunz's classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it appears with cubic, octahedral and dodecahedral rhomboid habit.
Fluorite exhibits thermoluminescence and fluorescence physical properties.
In industry, it is mainly used in iron and steel metallurgy. It is used as a source of fluorine and hydrofluoric acid, also in the glazing of ceramics and in the manufacture of optical glasses.
The beauty of the specimens makes it a highly appreciated mineral by museums and private collectors.
