FLUORITE FROM THE EMILIO MINE (ASTURIAS) MIXED WITH CHALCOPYRITE AND CALCITE CRYSTALS AND BARITE SHEETS WE CAN ALSO OBSERVE THAT IT HAS A LIGHT BLACK SHADE (NATURAL PETROLEUM). THE FLUORITE CRYSTALS ARE COMPLETELY TRANSPARENT AND OF A GOOD SIZE. PIECE OF VERY GOOD SIZE AND IDEAL FOR EXCLUSIVE COLLECTORS
Fluorite is a mineral of group III (halides) that, according to the Strunz classification, forms the elements calcium and fluorine.
Its structure belongs to the cubic system, and it appears with cubic, octahedral and rhombododecahedral habit.
Fluorite presents physical properties of thermoluminescence and fluorescence.
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.
