This is the synthetic form of Azurite (basic copper carbonate). See also Bice, Azurite. CAMEO notes that the particle shape is rounder and more uniform than ground Azurite, and looks more like Azurite in its finer grinds.

Stats
Lightfastness
May be reactive under certain conditions
Considered lightfast, but may react in various media. There are advisories that thick layers of azurite in oils may discolor, which may or may not apply to the synthetic version but it is good to keep in mind. Michael Price and others have done more extensive research on how to use Azurite as well as treatments to the pigment particles for use in painting. While not related to lightfastness, it is sensitive to acids, sulfur in the air, alkalis (warm), and Hydrogen sulfide.
