This is one of the more aesthetic specimens of Bournonite that I have seen from Bolivia. This piece hosts a large (3.5 x 2.4 cm), attractive, sharp, striated, tabular, silvery-grey color crystal sitting atop micro grey Quartz matrix. This specimen is from the find about 8 years ago, when some of the finest Bolivian Bournonites were collected. Ex. Brian Kosnar Collection.
