This is one of the more aesthetic specimens of Bournonite that I have offered from Bolivia. This piece consists of an attractive, sharp, doubly-terminated, striated, tabular, silvery-grey color crystal sitting atop micro Pyrite matrix. This specimen is from the find about 5 years ago, when some of the finest Bolivian Bournonites were collected. 2.7 x 2.3 x 1.9cm
