Malachite: Mineral information, data and localities.
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 ...

Malachite: The mineral malachite information and pictures
Malachite is a popular mineral with its intense green color and beautiful banded masses. The banded specimens are formed by massive, botryoidal, reniform, and especially stalactitic Malachite that are dense intergrowths of tiny, fibrous needles. Dense banded specimens are often sliced and polished to bring out their beautiful coloring. The bands may consist of concentric rings with interesting ...
