Description

Chrysocolla Tumbled Stones

Chrysocolla has a monoclinic cystal system and is in the mineral class of ring silicates. It is formed by a secondary process in the oxidation zone of copper ore where surface water that contains silicic acid dissolves the copper out of the rock. Because Malachite is formed in the same type of manner, it is not uncommon to find the two joined together.

It can crystalize in the form of crusts, layers, large masses and even needle-like crystals. It’s coloring can range from green to turquoise to blue shades, and is sometimes found with brown or black splotches. It can be found in the southwestern U.S., Mexico, Zaire, Russia, Peru and Afganistan.
