Azurite is an azure blue copper mineral, it is occasionally found as prismatic crystals, but is rarely ever faceted. More often it is found in massive form inter-grown with Malachite as a result of the weathering and oxidation of copper sulfide minerals. The name azurite comes from the Persian work lazhaward meaning blue, it is often used in jewelry and also collected as a beautiful mineral specimen. The ancient Greeks and Romans used ground forms of the stone for medicinal purposes and for dye.
