Malachite
Malachite is an intense green copper-bearing mineral notable for its characteristic band patterns and glass to silky luster. The colour ranges from light green to dark green, often with concentric or layered drawings. The mineral usually forms in the oxidation zones of copper deposits.
Major deposits include the Democratic Republic of Congo, Namibia, Russia, Australia and the United States. Malachite has the chemical formula Cu₂CO₃(OH)₂ and a hardness of 3.5 to 4 on the Mohs scale.
There are no official subspecies, but notable forms include botryoidal malachite (grape-shaped), needle-shaped malachite (silk malachite) and malachite with azurite, with the mineral occurring together with the blue copper ore form azurite.
