Recognizable by its brilliant blue to green tones, chrysocolla is a hydrated copper phyllosilicate with the approximate formula (Cu,Al)2H2Si2O5(OH)4 nH2O. It forms in the oxidation zones of copper deposits, commonly associated with malachite, azurite, and turquoise. The mineral is translucent with a vitreous luster and a white to pale-blue streak, showing no cleavage and a conchoidal fracture. Habits are botryoidal, massive, or stalactitic. Its hardness varies considerably, from 2 to 4, and its specific gravity from 1.93 to 2.40. Chrysocolla is worked as an ornamental stone, valued for the vivid turquoise-like coloration it draws from copper. Both its density and its hardness vary widely, reflecting a variable water content and frequent admixture with other minerals.

Chrysocolla is a hydrated copper phyllosilicate mineral known for its brilliant blue to green colors. It is commonly found in oxidation zones of copper deposits, often associated with malachite, azurite, and turquoise.
