Item Description
There was a find of this relatively rare copper sulfosalt last year at Machacamarca, and this piece is definitely one of the more attractive specimens to come out in this size range. This piece hosts a lovely, fairly thick, sharp, silvery-grey color, tabular crystal of Bournonite measuring 3.1 cm on micro grey Quartz matrix. This is an attractive specimen (especially for this mine), and displays very well. There was only one pocket from this mine that produced these larger tabular Bournonite crystals on matrix, so don't miss out. From what I have been told, this mine is not producing these specimens at the moment, and the last time the Bournonites stopped coming out, it took three years for the miners to find more.
