This large piece consists of two Azur-malachite crusts that partly coat a brown sandstone or shale base. One of these crusts has been ground smooth and polished to a glossy sheen. It shows no crystal form and the standard deep blue and pale green colors of the material. The other crust is rough, showing noticeable botryoidal form, and consists of a layer of Azurite that is coated by a thin malachite layer. They have the same deep blue and pale green colorations, but are completely dull in luster. There are many very small patches and veins of massive Azurite scattered elsewhere on the piece, and one vein in which it appears to be crystalline.
