SPECTACULAR FLUORITE FROM THE AREA OF BERBES, ASTURIAS. GOOD AND SUPER CRYSTALIZATION OF A SPECTACULAR TONALITY MIXED ON A BASE OF QUARTZ AND LARGE SIZE CRYSTAL OF DOG TYPE CALCITE. PERFECT CRYSTALIZATION 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.
