Azurite The blue gem material, ore of copper, and pigment.

Azurite is easy to cut and shape into cabochons, beads, small carvings, and ornaments. It also accepts a bright polish. Unfortunately, azurite has problems that limit its use in jewelry. The greatest concern is the fact that azurite has a Mohs hardness of just 3.5 to 4.0. It also is brittle and can break along cleavage planes.
