Two marvelous Calcite crystals on a Fluorite matrix, mixed with small Pyrite and Dolomite inlays. Caramel hue, combined with the characteristic white of Calcite. All this makes this an indispensable piece in a collector's showcase. Extracted from Mina Moscona, Asturias. Size approx. 9 x 9 cm and a weight of 251 gr.
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.
