TOTALLY TRANSPARENT FLUORITE CRYSTALS FROM THE EMILIO MINE IN ASTURIAS. IN THIS PIECE WE CAN SEE A TOTALLY TRANSPARENT CRYSTAL LIKE A GLASS WITH A LITTLE ATYPICAL FORMATION. VERY GOOD PIECE
Fluorite is a group III mineral (halides) that, according to the Strunz classification, forms the elements calcium and fluorine.
Its structure belongs to the cubic system, and is presented with cubic, octahedral and rhombic dodecahedral habits.
Fluorite exhibits 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, and also in the enamelling of ceramics and in the manufacture of optical glass.
The beauty of the specimens makes it a highly appreciated mineral by museums and private collectors.
