This is a major historical pseudomorph specimen, with great display and great provenance. Several intergrown crystals to a large 4 cm blade in front attached to vertical, parallel-growth "blades" chalcocite, have been altered to bornite which exhibits the slightly iridescent blue black and copper colors of that species. Ex. Nick Carruth and the Richard Barstow collections (Barstow obtained it from JL White).
