The host rock of this specimen is partially coated with a thin layer of bladed Atacamite crystals. They are flattened against the surface of the host, so that individual crystals cannot be studied clearly, but they have definite form and their radiating habit makes small "sunburst" designs in the crust. They have the deep green color and vitreous luster that are characteristic of this mineral, but are pressed too deeply into the host to determine their translucence or transparence. The host rock appears to have a concentration of iron in it, and has several black spots on it that make me think of decayed azurite, but I am not sure of either one's composition.
