SPECTACULAR PIECE OF FLUORITE CRYSTALS FILLED WITH PETROLEUM, WITH A BARITE FLOWER ON THE TOP. WE CAN ALSO OBSERVE A FILM ON TOP OF SOME PYRITE CRYSTALS AND ON THE BACK PART FILLED WITH DOG-TOOTH TYPE CALCITE CRYSTALS WITH HORIZONTAL CRYSTALS. VERY GOOD PIECE THAT WE ACTIVATED FOR THE SALE OF A PRIVATE COLLECTION.
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 is presented with a cubic, octahedral and rhombododecahedral habit.
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, also in the enameling 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.
