Overview of Malachite
About
Malachite is a copper carbonate hydroxide mineral known for its striking green color and distinctive banding. It forms in the oxidation zones of copper deposits and is often found in botryoidal, stalactitic, or fibrous masses. Its rich green hues can range from light to dark, with intricate patterns of concentric circles or stripes, making it a favourite among collectors and lapidary artists.
