What is Azurite?

Azurite is a deep blue copper carbonate. It serves as a minor ore of copper. It is also a popular gem and ornamental stone because of its blue color. Azurite's low hardness limits its use as a gem and as an ornamental stone. It is often found in association with malachite in the oxidized zone above copper deposits.
