SPECTACULAR LARGE PIECE WITH FLOATING FLUORITE CRYSTALS WITH PYRITE SPECKLES DISTRIBUTED THROUGHOUT THE PIECE. IN THE BACK WE CAN SEE CALCITE CRYSTALS AND SOME MOTES OF DOLOMITE. VERY GOOD PIECE THAT CANNOT BE MISSING IN YOUR COLLECTION.
Fluorite is a group III mineral (halides) that according to the Strunz classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it appears with a cubic, octahedral, and rhombododecahedral habit.
Fluorite has physical thermoluminescence and fluorescence 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 mineral much appreciated by museums and private collectors.
