Native copper. Native copper is pure copper as found in nature. Copper is one of the few metallic elements to occur in unmixed form as a natural mineral,although it most commonly occurs in oxidized states or mixed with other elements. The isometric crystals of this sample,forming a dendritic pattern,are rare. Native copper used to be an important ore of copper from pre-historic times onwards,but is now more a collector's item | |
