This is an opaque, green banded mineral in the monoclinic crystal system (a rectangular prism with a parallelogram as its base) of copper carbonate hydroxide mineral, but it is often found together with azurite, goethite, and calcite. Most often it can be found in globular or fibrous forms, or as stalagmitic masses, in fractures and spaces, deep underground, where the water table and hydrothermal fluids provide the means for chemical precipitation. Archeological evidence indicates that the mineral has been mined and smelted to obtain copper at Timna Valley in Israel for over 3,000 years. Since then, polished malachite has been used as both an ornamental stone and as a gemstone. Malachite was used as a mineral pigment in green paints from antiquity until about 1800. The stone is found worldwide in Russia, Mexico, Australia, United States, and several countries on the African continent.
