Physical properties
Hardness of 2.5 to 3.5 on the Mohs scale, vibrant cyan to bluish-green color, vitreous to earthy luster, and an amorphous or cryptocrystalline crystal structure.
Formation & geological history
Forms as a secondary mineral in the oxidation zones of copper ore bodies, typically precipitated from copper-rich fluids in arid environments.
Uses & applications
Used primarily as a minor ore of copper, as an ornamental stone, and in lapidary arts for cabochons and jewelry.
Geological facts
Chrysocolla is often found mixed with quartz, malachite, and azurite, creating striking multicolored patterns known as eilat stone or gem silica when quartz-impregnated.
Field identification & locations
Identified easily by its bright turquoise-blue color and softness, commonly found in major copper-producing regions like Arizona, Chile, and Peru.
