Basic Copper Carbonate occurs naturally in two crystalline forms, blue (azurite) and green (malachite). Azurite and malachite have been used as gemstones and paint pigments since antiquity. They are prepared as pigments by careful selection, grinding, washing, and levitation. As coarsely ground particles, they give a deep opaque color, but when finely ground, the pigments give a lighter more transparent tone. Azurite and malachite are lightfast but are sensitive to acids and sulfur fumes. Basic copper carbonate can also be made artificially by coloring chalk with copper sulfate. The equivalent synthetic pigments, called blue and green, tend to have regularly sized particles with rounded edges.
