Formula: Cu2(CO3)(OH)2; Hardness: 3.5 - 4; Color: Light to very dark green; Crystal System: Monoclinic; Malachite is a green, very common secondary copper mineral with a widely variable habit. Typically it is found as crystalline aggregates or crusts, often banded in appearance, like agates. It is also often found as botryoidal clusters of radiating crystals, and as mammillary aggregates as well. Single crystals and clusters of distinguishable crystals are uncommon, but when found they are typically acicular to prismatic. Its name could have come from the Greek word, "malache" which means "mallow", because the colour of malachite is similar to the colour of mallow leaf. Alternatively, the name could have originated in the Greek word, "malakos", which means "soft", due to the fact that malachite is soft compared with other minerals. Malachite is used as a source of copper and as a gemstone. (The above information is provided solely for informational purpose. Kindly note that all stones are offered for decorative purposes only.
