Azurite: a fascinating mineral species
The mineral species Azurite is a monoclinic anhydrous carbonate of Copper with the composition Cu3(CO3)2(OH)2. Azurite is mostly a secondary mineral typically found in oxidized zones of Copper-bearing metallic ore deposits. It is often found pseudomorphed to Malachite, also a monoclinic anhydrous carbonate of Copper with the composition Cu2CO3(OH)2. Azurite is a favorite among mineral collectors because of its sharp and very lustrous prismatic and tabular crystals of deep blue colour.
Its name was originally derived from the ancient Persian word lazhward, meaning "blue", in allusion to the color. The name was later changed to Azurite in 1824 by Francois Sulpice Beudant.
There are over five thousands known localities worldwide (currently 5437 reported localities on mindat.org) where Azurite has been identified. There are many excellent localities worldwide to find great Azurite specimens for their crystal size, perfection and gemminess. Currently, a large number of great specimens of interest to collectors are coming from China, Mexico, Morocco, Namibia and United States.
Collectors who wish to investigate further the geology and mineralogy of Azurite and find excellent photographs of this colourful mineral species are invited to consult the mindat.org website as well as the Mineralogical Record publications.
