Chalcanthite ex. Urish Coll.

Item Description

A rare specimen of chalcanthite, from Bisbee! While the possibility exists for this species to be post-mining, we believe this was naturally formed in the mine in historic times and not from manmade activity as those specimens tend to be different in form. The piece is sparkly an dattractive. From the well known Tucson collection of 40-year collector, Harold Urish.
