Malachite, also known as copper patina as well as mountain or copper green, is a mineral from the mineral class of 'carbonates and nitrates' with the chemical composition Cu2[(OH)2|CO3][4]. Chemically, it is a basic copper carbonate.

Malachite crystallizes in the monoclinic crystal system, but very rarely forms visible crystals to the naked eye with needle-like to prismatic habits. It is usually found in massive or botryoidal, banded aggregates in an exclusively green color, ranging from pale to dark green.

Already Pliny the Elder (23/24–79) described malachite in his work Naturalis Historia. The name likely derives from the Latin molochitis, probably from the Greek word μαλάχη, in ancient Greek pronunciation maláchē, meaning 'mallow.' The color of the stone is said to resemble the vibrant green of the leaves.

Already in ancient Greece, ancient Egypt, and the Roman Empire, the mineral was extremely popular. The Egyptians carved various art objects from malachite, such as amulets and scarabs, and processed the finely ground mineral into expressive eye shadows. Contrary to earlier assumptions, it now seems very likely that malachite was not used as the basis for the green color in wall paintings in ancient Egyptian tombs, according to more recent research.
