• Azurite owes its name to its beautiful azure-blue color, which makes it a very popular and well-known mineral. Azurite often occurs with green Malachite, which may form green stains or specks on Azurite crystals or aggregates. The two minerals sometimes occur admixed or banded together, forming what is called "Azure-malachite" in the gem and mineral trades. A rarer Azurite mixture, known as "Bluebird", is Azurite mixed with dark red Cuprite. Azurite, "Azure-malachite", and "Bluebird".
• Azurite precipitation occurs in pore spaces, fractures, and cavities of the subsurface rock. The resulting azurite is usually massive or nodular. In rare situations, azurite is found as stalactitic and botryoidal growths. Well-formed monoclinic crystals are infrequently found. These can only occur if azurite precipitates unrestricted in a fracture or cavity and is not disrupted by later crystallization or rock movements.
