This particular specimen has a rather special addition to it. One one side of the relatively flat base rock is a thick coating that consists of hundreds of radiating Aurichalcite crystals. These crystals are about as thin as human hair and reach about 4 mm in length. They have a bright, sky-blue color and a pearly luster, and are translucent. The crust is in good condition, showing surprisingly little damage. It rests on a gray-brown host rock that is intermixed with small amounts of more Aurichalcite and what appears to be hemimorphite, and a rather impressive amount of yellow-green smithsonite that shows good botryoidal form. Parts of the smithsonite cluster are covered with thin white or brown crusts that don't interfere with its shape. The documentation that we recieved said nothing about the smithsonite, which surprised me because it is rather obvious, though coating what can be considered the "underside" of the specimen.
