A completely transparent fluorite specimen, mixed with dolomite and micro-calcite crystals, from the Emilio mine in Asturias. A very high-quality piece with crystals of all types. On both sides, inclusions of crystallized petroleum can be observed within the crystals. A piece for new collectors.
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 prized mineral by museums and private collectors.
