BEAUTIFUL FLUORITE WITH CALCITE CRYSTALS FROM THE BERTA MINE, PAPIOL, BARCELONA (CURRENTLY CLOSED MINE). VERY ATTRACTIVE PIECE ON ITS MATRIX, WITH SAMPLES OF FLUORITE CRYSTALS OVER THOSE OF CALCITE.
Fluorite (also called fluorine or fluorine) is a mineral of the halide group, formed by the combination of the elements calcium and fluorine.
This mineral normally crystallizes in a cubic, octahedral, dodecahedral shape.
It is a mineral that has thermoluminescent and fluorescent properties (ultraviolet rays).
