Beautiful cluster of golden pyrite cubes in natural matrix, collected from Navajún, La Rioja, Spain. A natural work of art and a great display piece.

The crystal system is called isometric, or cubic, meaning that its smaller molecules form cubes. These specimens are roughly 130 millions years old. They are mined about 3 hours northeast of Madrid, in Navajún, La Rioja, Spain. 

SPANISH PYRITE IS FAMOUS FOR ITS CUBIC SHAPE. 

IT IS COMPLETELY NATURAL - NOT CUT OR POLISHED!
