Large single Bournonite crystal 3.5cm wide from recent finds in Bolivia. The Bournonite crystal has a dark patina and classic 'cogwheel' form. Complete and perfect with some edge chipping. Presents perfectly on a small amount of matrix. The matrix is covered by tiny Quartz crystals and shiny Pyrite crystals making it visually exciting from any side. This is just how I received it, and the metallic luster could possibly be improved with cleaning. Valued at $150 as is.
