Viboras Mine, Machacamarca, Machacamarca District (Colavi District), Cornelio Saavedra Province, Potosi Department, Bolivia
A pair of very well-formed, sharp, semi-lustrous, soft metallic grey colored tabular blades of Bournonite are intergrown to create this eye-catching little display specimen. The crystals are virtually damage free, save for a very small contact on one edge. For an added touch, the crystals are associated with micro grey Quartz. Great quality and rather aesthetic for the material. From a find in June of 2007.
