2.6" Native Copper - Morocco

This is a 2.6" long, natural formation on native copper mined from the Oumjrane Mines in Morocco. There is some green oxidization on the specimen, as well as small amounts druzy quartz between some of the branching copper.

Native copper is an uncombined form of copper that occurs as a natural mineral. Copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements. Native copper was an important ore of copper in historic times and was used by pre-historic peoples.

Native copper occurs rarely as isometric cubic and octahedral crystals, but more typically as irregular masses and fracture fillings. It has a reddish, orangish, and/or brownish color on fresh surfaces, but typically is weathered and coated with a green tarnish of copper carbonate.
