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 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.
