- Azurite — A natural basic copper carbonate mineral with a monoclinic crystal structure, characterized by an intense, glossy, vitreous blue color and a famous chemical instability, often transforming into malachite under the influence of moisture. This structural mineral is found in the oxidation zones of copper ore deposits, historically used as a fine paint pigment and currently as a semi-precious stone for jewelry or decorative objects.
