These azurite crystals are from the Milpillas Mine in Cuitaca, Mun.de Santa Cruz, Sonora, Mexico. Mining at this locale began in 2006 with the extraction of copper minerals. Thirty-six mineral species have been identified at the mine including world class azurite and malachite. They are secondary copper carbonates containing the elements Cu, C and O and Ca, C, O and H respectively. Mining started in several copper oxide zones where the carbonate minerals were found. This specimen has a base of fibrous malachite with minor quartz attached that is sawed on the bottom surface. The malachite is topped with large spearhead shaped azurite crystals and partially altered azurite crystals. This specimen measures 3 x 1 3/4 x 1 3/4 inches or 76 x 45 x 45 mm as displayed in photo 4.
