the history of
Pyrite cubes
Spanish Pyrite is famous for its cubic shape. It is completely natural – Not cut or polished!
Pyrite is iron sulfide (Fe2 Iron (II) disulfide). The crystal system is called isometric, or cubic, meaning that its smaller molecules form cubes.
These specimens are roughly 130 million years old.

Mineralogy
In the entire area of the deposit, apart from pyrite, only gypsum, chlorite and some manganese minerals have been found. Pyrite occurs almost exclusively in cubic form and very rarely in cubo-octahedral crystals. Also pyritohedra. Some specimens with beveled edges also come from Navajún. The sizes are between the millimeter and 20 cm. edge, between which all intermediate measures can be given.
