Malachite is a mineral composed of hydrated copper carbonate₂. It belongs to the carbonate group and is usually formed in oxidation zones of copper deposits. Malachite is easily recognizable by its characteristic green color, which can vary from light green to dark green. This coloration is due to the presence of copper in its crystalline structure. Malachite specimens often have concentric bands of green color, creating aesthetic patterns that are highly valued in jewelry and decoration. The formation of malachite is related to the weathering of copper minerals by water and oxygen. This weathering process, called oxidation, usually occurs near the Earth's surface. Malachite deposits are often associated with other copper minerals, such as azurite and cuprite. Its intense green color and distinctive patterns make it a popular ornamental stone. It has been used since ancient times for jewelry, sculptures, and decorative objects. Due to its copper content, malachite has been mined as a copper ore in some parts of the world.
