Photo by Jim Bryan This specimen is on display at the California State Mining and Mineral Museum in Mariposa, CA. Azurite (Cu3(CO3)2(OH)2) is a very minor ore of copper. It is usually associated with (and over time weathers into) Malachite.Because of its widespread availability, historically it was often used as a blue pigment. The bright blue color gives it a high ornamental value, but its softness and sensitivity to heat and light tends to limit its use in jewelry.
