Azurite with Chrysocolla is a naturally occurring combination of stones with beautiful, vivid color and powerful energy. Azurite opens the door to inner discovery. It is connected to the Third Eye Chakra – the place of our deep intuition and inner guidance. Azurite and chrysocolla are both types of copper-based minerals, often found next to each other. They are known for their vibrant colors, with azurite displaying a deep blue, whereas chrysocolla will be more of a bright blue to green. This is a specimen that will contain both of these minerals. Chrysocolla has a cyan (blue-green) color and is a minor ore of copper, having a hardness of 2.5 to 7.0. It is of secondary origin and forms in the oxidation zones of copper ore bodies. Associated minerals are quartz, limonite, azurite, malachite, cuprite, and other secondary copper minerals. Azurite has a Mohs hardness of 3.5 to 4. The specific gravity of azurite is 3.7 to 3.9. Characteristic of a carbonate, specimens effervesce upon treatment with hydrochloric acid. The combination of deep blue color and effervescence when moistened with hydrochloric acid are identifying characteristics of the mineral. Azurite is commonly found in association with malachite and other copper minerals in oxidized copper ore deposits. It is used as a gemstone and as a pigment for paints and dyes. No, azurite is copper carbonate and chrysocolla is copper silicate - so they have different composition, chemical properties and appearance. They can occur together as they are both secondary copper minerals = they are formed by weathering of primary copper ores like chalcopyrite or bornite The rarest and best quality is chrysocolla chalcedony with turquoise-like colour, but harder and chemically more stable than turquise. It comes from several copper mines in Arizona, Mexico, Taiwan and Peru. See also: Eilat Stone, a blue-green gem material from Israel that contains Chrysocolla.
