Chrysocolla is attractive blue-green. It is perhaps more appropriately a mineraloid than a true mineral. Chrysocolla forms in the oxidation zones of copper rich ore bodies.
Pure chrysocolla is soft and fragile and usually not appropriate for use in jewelry. However, chrysocolla often is "agatized" in chalcedony quartz and it is the quartz that provides the stone with its polish and durability. Druzy Chrysocolla is a rock composed of agatized chysocolla with a crust of small sparkling quartz crystals in small cavities. A skilled craftsman, if able to polish a specimen that accentuates the colored swirles of chrysocolla and sparkles of the druzy quartz, can produce a lovely and valuable piece of jewelry. Occasionally, chrysocolla can have a turquoise color and be used as a fraudulent substitute for the more precious stone.
Chrysocolla is reputed to soothe nervous tension.
