What is malachite?

Malachite is a carbonate mineral, copper(II) carbonate hydroxide Cu2 CO3 (OH)2. It crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses. Individual crystals are rare, but do occur as slender to acicular prisms. Pseudomorphs after more tabular or blocky azurite crystals also occur.

Malachite often results from weathering of copper ores and is often found together with azurite (Cu3 (CO3)2 (OH)2), goethite, and calcite. Except for the vibrant green colour, the properties of malachite are very similar to those of azurite. Aggregates of the 2 minerals together are frequently found, although malachite is more common than azurite.

malachite pattern
The stone's name derives (via Latin and French) from Greek molochitis, "mallow-green stone", from moloche, variant of malache, "mallow".

Malachite was used as a mineral pigment in green paints from antiquity until about 1800. The pigment is moderately lightfast, very sensitive to acids and varying in colour.
