This is one of the more aesthetic specimens of Bournonite that I have offered from Bolivia. There was a find of this relatively rare copper sulfosalt about 6 years ago at Machacamarca, and this piece is one of the better quality pieces found. This piece features attractive, sharp, lustrous, tabular, silvery-grey color crystals associated with minor micro Pyrite and Quartz. There was only one pocket from this mine that produced these unusual Bournonite crystals with micro Pyrite and Quartz. Very choice for this mine.
