Aesthetic groups of chalcopyrite crystals with clusters of delicate siderite crystals from Kaiwu. The chalcopyrite crystals are sharp, and lustrous. The siderites are all over this one and provide a lot of texture. The chalcopyrite group at the top is super - sharp, well defined, with simple mirror-bright faces, intergrown crystals. Virtually no damage - tiny nicks to a couple of siderites, but not at all obvious - and an area of former attachment at the bottom on the left. Beautiful high quality specimen.
