This is an unusually fine, seafan-like, large, and completely crystallized specimen of copper from the classic Bisbee locality! Old Bisbee pieces have become rarer and rarer with each passing decade and, despite the tonnage of copper ore mined at the locality, have always been rare even at the source. I bought these four specimens from the briefcase of an Arizona collector who brought them to the show (Evan Jones). 6.8 x 5.4 x 2.1 cm
