Description

Pretty turquoise blue chrysocolla in association with cerussite. There are some nice cerussite crystals on the reverse side also. At one end of the specimen there is some unusual banding, probably due to varying conditions during deposition, and some minor malachite.  A nice combination and locality piece.
