Cabinet specimen, an old-timer generally not seen on the market these days. Botryoidal green Mimetite. The green is darker than the photos depict. The digital camera just plays games with color on arsenates. The Wulfenite is nice and the large one in the third photo is 1cm on end. Some of the crystals are broken. The last three photos are from the backside. The little colorless crystals all over it are selenite.
