Pyrite Cube on Basalt from Navajún, La Rioja Province, Spain (2.1 lbs)

Sharp cubic metallic pyrite crystal in tan-colored Basalt matrix. The pyrite crystal has smooth crystal faces with almost mirror-like luster, stands upright nicely without additional support. 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.
