What is Azurite
Azurite is a copper carbonate mineral that forms in the oxidized portions of copper ore deposits. It is commonly found in association with malachite, another copper mineral, creating a stunning blend of vibrant blues and greens. The striking azure-blue hue color of the gem is due to the presence of copper ions within its crystal structure. When light interacts with azurite, it absorbs all colors except blue, resulting in its characteristic deep blue shade. Azurite is a popular gemstone used in making jewelry and other ornaments.

It is also useful in meditation practices, either held or placed on the third eye chakra, to deepen the connection with one’s inner self and expand consciousness.
What is Malachite
Malachite is a green-colored copper carbonate mineral that forms in the oxidized zones of copper ore deposits. It is often found in association with another copper mineral, azurite, resulting in an enchanting blend of vibrant blues and greens. The gemstone owes its vibrant green color to the presence of copper ions within its crystal structure. Malachite’s characteristic bands and swirls are created by its unique growth patterns, which add to its allure and individuality.
