Malachite is a green copper carbonate mineral that belongs to the monolithic crystal system. It has a silky luster and opaque transparency. The rich shade of green in malachite symbolizes transformation and positive change. Malachite is often found in patterned surfaces and can contain traces of blue or black. It is formed above copper deposits deep in the earth and is typically found alongside other minerals such as azurite, calcite, and iron oxides.
