Copper Chloride Mineral
Atacamite is a vivid green copper chloride mineral that forms sparkling crusts, needle-like crystals or drusy coatings on host rock. Its intense colour and association with arid, sun-baked copper deposits make it a popular choice for heart-healing work, honest communication and gently energising emotional release.

Origin & History

Where Atacamite comes from and how people have worked with it over time.

Atacamite forms as a secondary mineral when primary copper sulphides and other copper-bearing minerals break down in very dry, salty environments. Evaporating groundwater and oxidising conditions allow copper, chlorine and hydroxyl to recombine into vivid green atacamite. It was first described from the Atacama Desert region of Chile, one of the driest places on Earth, which gave the mineral its name. Today, notable specimens also come from Australia, Namibia and other copper-rich deposits around the world. Because of its softness and brittle nature, atacamite is more commonly seen in collections and carefully set jewelry than in heavy everyday wear.
