Azurite is hydrated copper carbonate; its chemical formula is Cu3(CO3)2(OH)2. Malachite (another copper-based mineral) and azurite are often found together. Azurite has a hardness of 3.5 to 4 (relatively soft) and a specific gravity of 3.7 to 3.9. Azurite is found in massive monoclinic crystals in Australia the southwestern USA, France, Mexico, Morocco, Nambia, Zaire, and Europe. Azurite is sometimes coated with a colorless wax or impregnated with plastic in order to enhance the color and increase the hardness.

(1868, from azur, the French word for "azure", the blue colour of the clear sky) Azurite is a solid deep blue mineral consisting of basic carbonate of copper. It is found in a variety of forms including massive pieces, nodules and crystallized clusters. Too soft to be used as an ornamental stone, azurite was used in ancient times (and even today) as a colour pigment. Although it is rarely available in cut form the stone has a strong lustre when cut and polished.
CU3(CO3)2(OH)2 Azurite is a secondary ore of copper and usually associated with malachite, and is part of the carbonate group. Malachite and azurite are formed in the same way, but azurite is a bright blue and is the rarer of the two minerals. Sources are Arizona, Africa, Australia, and France.
