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 is a rather lustrous, sharp, silvery-grey color, tabular crystal with good form. The piece is complete most of the way around, and is well formed compared to most I have seen from this mine. This is an attractive specimen due to the higher luster, (the majority of the Bournonites from Machacamarca have a dull luster typically) 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.
