Azurite is a beautiful blue mineral that is commonly found in copper mines. It is a copper carbonate mineral that has a deep blue color and is often found with other copper minerals such as malachite. Azurite is a soft mineral with a Mohs hardness of 3.5 to 4 and a specific gravity of 3.77 to 3.89. It has a bright blue streak and a vitreous to dull luster. Azurite is often confused with lapis lazuli, which is a rock composed of several minerals including lazurite, but azurite is a distinct mineral with its own unique properties.

It can be distinguished from other blue minerals by its softness and the fact that it is easily scratched by a fingernail. Azurite is also soluble in acids, which can be used to distinguish it from other copper minerals.
