Viboras Mine, Machacamarca mining dstrict, Cornelio Saavedra Province, Potosi, Bolivia
Cluster of sharp, lustrous bournonite, the dominant crystals each measuring 2cm across. Contacted at the back but in excellent condition and displays beautifully from the front and sides. The patchy brownish hue is exaggerated by the camera and not so evident to the naked eye. From a 2019 find at this classic locality with notably large and well developed crystals. Very three dimensional, striking and highly aesthetic.
