This rather simple specimen consists of a thick slab of brown host rock that has three hollows, all of which are partially coated with a thin Malachite crust. The Malachite has the standard dark-green color and silky-to-pearly luster that is common. There are many round, botryoidal nodules emanating from the crust (see the close-up image)- some of these nodules are broken or only partially-formed, and one can see that they are made up of many radiating, needlelike crystals. There are a few small patches of a pale-blue material that could be any one of a variety of minerals, but are probably made of chrysocolla. There is also a very thin layer of a dull, pale gray material that is sandwiched between the Malachite and the host rock. I have no idea what it may be.
