About four months ago, there was a new find of Bournonites at Machacamarca, and these are some of the best pieces to come out in a long time. This specimen is a fine miniature from the find featuring a sharp, steel-grey color, lustrous, rather thick blade of Bournonite sitting atop smaller bladed, somewhat etched Bournonite matrix. The main Bournonite crystal is in excellent condition and is one of the best examples of this material to hit the market in at least 10 years. Ex. Brian Kosnar.
