WE PRESENT THIS SPECTACULAR PIECE OF FLUORITE CRYSTALS WITH GIANT CALCITE CRYSTALS AND SOME DOLOMITE FLOWERS. SEMI-TRANSPARENT CALCITE CRYSTALS OF VERY GOOD QUALITY. ON ONE SIDE WE OBSERVE FLUORITE CRYSTALS IN PERFECT CONDITION WITH A CARAMEL TONE.
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 appears with cubic, octahedral and dodecahedral rhomboid habit.
Fluorite exhibits thermoluminescence and fluorescence physical properties.
In industry, it is mainly used in iron and steel metallurgy. 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.
