    • n malachite A basic carbonate of copper having a beautiful green color, hence commonly called the green carbonate of Copper. It occurs rarely in tufts of slender monoclinic crystals, more frequently massive with mammillary, stalactitic, or granular structure, often fibrous and radiated. The finest specimens come from the Siberian mines. It is also common in Cornwall and in South Australia, Arizona, etc. It takes a good polish, and is manufactured into ornamental articles. It is often called green malachite, in distinction from blue malachite, or azurite, which is a related carbonate of copper containing less water, and which often passes by alteration into the green carbonate. See azurite.
