07807 - Beautiful Deep Blue Azurite Crystals on Carbonate Matrix - Kerrouchen (Morocco) Campo del Cielo (IAB-MG) Enchodus pulchellusAzurite is one of the two basic copper carbonate minerals, the other being bright green malachite. Simple copper carbonate (CuCO3) is not known to exist in nature. Azurite has the formula Cu3(CO3)2(OH)2, with the copper cations linked to two different anions, carbonate and hydroxide. Small crystals of azurite can be produced by rapidly stirring a few drops of copper sulfate solution into a saturated solution of sodium carbonate and allowing the
