Chemical Formula: Cu3(CO3)2(OH)2

Chemical Name: Hydrated Copper Carbonate

Mineral Class: Carbonate

Mineral Notes: Azurite is named from the Arabic word for blue, reflecting the intense blue colour. The colour is very distinctive, although the shade varies among specimens. It is formed by the action of carbon dioxide and water on primary copper sulfide ores. The mineral was occasionally mined as an ore of copper, but its main use was always as a pigment. Azurite forms many different crystal habits including fine crystal clusters, nodules and beautful combinations with its closely related cousin Malachite.

Description: A very rich specimen of Azurite on matrix. Some Malachite is also present. The Azurite forms numerous spherical clusters in which individual crystals are easily seen. The mineral has the characterisitc deep-blue colour and an extremely strong glassy luster. A very striking display specimen.
