Chrysocolla is attractive blue-green that provides a unique color to the mineral world. Chyrsocolla is perhaps more appropriately a mineraloid than a true mineral. Most of the time it is amorphous meaning that it does not have a coherent crystalline structure. However at higher temperatures it does demonstrate a distorted crystal structure that seems to be composed of Si4 O10 sheets. Chrysocolla forms in the oxidation zones of copper rich ore bodies. The name Chrysocolla derives from Greek chrysos - gold and kolla - glue, referring to its use as a flux in soldering gold. The term was used from antiquity. Chrysocolla is often found in a matrix of quartz, in which case the optical and physical properties may be closer to those of quartz. Chrysocolla covered by druses of small sparkling quartz crystals is called "Drusy Chrysocolla" and is very popular for jewelry. It is found in Peru.
