There was a find of this relatively rare copper sulfosalt about 6 years ago at Machacamarca, and this piece is definitely one of the more unique to come out in this size range. This piece features several, attractive, sharp, lustrous, tabular, silvery-grey color crystals of Bournonite on Siderite and Quartz matrix. This is actually an attractive specimen (especially for this mine), and displays very well.
