SPECTACULAR PIECE OF FLUORITE CRYSTALS, MIXED WITH SMALL CALCITE CRYSTALS (DOG'S TOOTH) AND PETROLEOP SPECKLES WITHIN THE CRYSTALS. IN THIS PIECE IN THE UPPER PART WE CAN SEE A LARGE SIZE CRYSTAL OF FLUORITE WITH A LIGHT BLUE SHADE OF A GOOD FINISH.
Fluorite is a group III mineral (halides) that according to the Strunz classification, formed the elements calcium and fluorine.
Its structure belongs to the cubic system, and it appears with a cubic, octahedral, and rhombododecahedral habit.
Fluorite has physical thermoluminescence and fluorescence 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 mineral much appreciated by museums and private collectors.
