Bournonite ("cogwheel")

Item Description

One of the few "cogwheel" specimens of Bournonite that I have offered from Bolivia in the auctions in months. This piece is an attractive, sharp, thick, tabular, metallic, silvery-grey color, lustrous, "cogwheel"-shaped crystal group. This specimen is from a find last year in Bolivia, with the exception of a few rough spots, is in great shape overall from the standpoint of damage.
