STUNNING AZURITE CLUSTER

The blue color in Azurite is much sought after by collectors. It has been used as a stain for centuries. It is sometimes replaced by malachite to form interesting psuedomorphs.
The mineral azurite, the basic carbonate of copper, is used as a decorative stone and a blue pigment. Azurite occurs in the oxidized zone of copper deposits, where it has been precipitated from low-temperature copper and carbonate-rich solutions. It is almost always associated with the more abundant green copper carbonate malachite, to which azurite weathers. It forms modified monoclinic crystals as well as columnar or earthy masses that have a vitreous luster and a distinctive azure-blue color.
The richest pockets of azurites were found in the eighties at Tsumeb, Namibia. Crystals were found at the upper zones in the oxidation zone.
