Pyrite Cube from Navajún, La Rioja Province, Spain (266 grams)

A large cubic pyrite crystal across intergrown with several smaller cubic pyrite crystals with no matrix attached. The pyrite crystals have smooth faces and sharp edges, typical of this prolific mine. A must-have for any collection, these unique formations are formed through a process of precipitation and crystal growth within sedimentary and metamorphic rocks, taking millions of years and resulting in nearly perfect cubic-shaped crystals.
