#azurit
- 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.
- Azurite-blue — A secondary feminine form of the adjective azurat or a rare substantivization describing a specific shade of a deep, glassy blue resembling the mineral azurite. In literary and stylistic texts, the term characterizes reflective surfaces, deep waters, or nocturnal celestial vaults that borrow the intense mineral brilliance of oxidized copper.
