Bournonite

Item Description

Several months ago, there was a find of this relatively rare copper sulfosalt at Machacamarca, and this piece is definitely one of the more attractive specimens to come out in this size range. This piece hosts a few lovely, sharp, silvery-grey color, tabular crystals with good luster The crystals are associated with minor micro Quartz and Pyrite. Many of the crystals are well-formed, and with a bit of roughness where it detached from the pocket wall. This is an attractive specimen (especially for this mine). 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. Valued at $600 in the inventory.
