This large cabinet specimen consists of a brown shale host rock through which extend many thin veins of massive Azurite and malachite. One of these veins has been completely exposed, making up part of the surface of the piece. It has been ground smooth and polished to show the interaction between the Azurite and malachite. The Azurite is the more pervasive of the 2 minerals, and has the classic dark blue coloration that is nearly black in many areas. The malachite has the standard pale to moderate green coloration, and subtle banding can be seen with close inspection. The crust is essentially opaque.
