SPECTACULAR FLUORITE OF GREEN TONE FOUND IN THE ROMAN MINES OF SANT MARÇAL, MIXED WITH CALCITE CRYSTALS FROM THE MONTSENY MOUNTAIN (BARCELONA). SPECTACULAR CRYSTALS AND ABSOLUTE PERFECTION. MINES CLOSED AND VERY HARD TO FIND CURRENTLY
Fluorite is a group III mineral (halides) that, according to Strunz's classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it has a cubic, octahedral and dodecahedral rhomboid habit.
Fluorite exhibits thermoluminescence and fluorescence physical properties.
In industry, it is mainly used in the metallurgy of iron and steel. 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 highly appreciated mineral by museums and private collectors.
