Description
A full-sized miniature specimen hosting several thick bladed crystals of metallic grey color Bournonite on a small layer of grey/white micro-crystallized Quartz. There is certainly a fair amount of Bournonite on this specimen, and it is a small miracle that the piece was not completely destroyed in the blast when it was found, let alone the fact that the crystals stayed on matrix!
