Bournonite (unique specimen) / Locality - Viboras Mine, Machacamarca, Potosi Department, Bolivia


Shipping to United States: Free

A really interesting and certainly unique display specimen of Bournonite from this famous locality. This piece is unlike anything I have offered from Machacamarca, as it features wonderful, sharp, lustrous, layered, tabular, gun metal grey color crystals which are sitting atop lustrous, striated black crystals of Sphalerite with minor greenish-brown Siderite. A great association specimen of this well-known material, and we really went crazy with the photos on this one because it has so much going on. With so many average quality Chinese Bournonites on the market, these Bolivian pieces might get lost in the mix, but when they're good, they are very impressive. This piece was found in early 2009, and was actually part of my personal collection for a time.
