The Copper Carbonate Matrix
Malachite is famous for its lush, opaque green color and intricate banding, resembling the concentric rings of a tree. It forms in the oxidation zone of copper deposits, often alongside azurite.
A Favorite of the Ancients
Ancient Egyptians utilized malachite for amulets and ground it into green pigment for eye makeup. In 19th-century Russia, massive malachite blocks were carved into entire columns and vases for the Winter Palace.
Working with Malachite
With a Mohs hardness of 3.5-4, it is quite soft. Lapidarists must take extreme care: its dust is toxic due to copper content. It should only be shaped using a wet grinder with strict air-filtration protocols in place.
