WE PRESENT THIS GROUP OF FLUORITE CRYSTALS FROM THE GEODE OF LAS MONJAS IN LA VIESCA. GLASSES OF A VERY GOOD TONALITY TYPICAL OF THIS AREA OF LA VIESCA. LARGE SIZE CRYSTALS
Fluorite is a group III mineral (halogenides) 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 the metallurgy of iron and steel. It is used as a source of fluoride and hydrofluoric acid, also in the enameling of ceramics and in the manufacture of optical glasses.
