Malachite is a copper carbonate mineral.
This green-coloured mineral crystallizes in the monoclinic crystal system, and most often forms botryoidal, fibrous, or stalagmitic masses.
The stone's name derives (via Latin: molochītis, Middle French: melochite, and Middle English melochites) from Greek Μολοχίτης λίθος molochitis lithos, "mallow-green stone". The mineral was given this name due to its resemblance to the leaves of the Mallow plant.
