Sharp and rather sculptural, this pseudomorph is from the famous Yaogangxian Mine is China. The 3.5 cm, rectangular prism of Bournonite has been replaced by Boulangerite, and that pseudo is, in turn, liberally coated with brassy Chalcopyrite crystals. All rest on a single Quartz spear, creating an interesting, architectural look, for sure. A fine specimen, it is even better in person.
