Bournonite

Item Description

There was a find of this relatively rare copper sulfosalt a few months ago at Machacamarca, and this piece is definitely one of the more attractive specimens to come out in this size range. This piece is an attractive, sharp, tabular, metallic, silvery-grey color crystal. It is certainly good sized for this material, and fairly complete compared to many others which were simply partial crystals at best. It is well-formed with decent luster in areas, and some sharp modifying faces around the periphery. Valued at $800-$1000 retail.
