FLUORITE SAMPLE FROM MOSCONA WITH CALCITE CRYSTALS AND DOLOMITES. SMALL GEODES FILLED WITH TOTALLY TRANSPARENT CRYSTALS WITH A LIGHT CANDY TONE. LARGE CALCITE CRYSTALS.
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.
