Bolivia

Viboras Mine, Machacamarca, Cornelio Saavedra Prov., Potosí, Bolivia
SIZE
68 x 49 x 34 mm
DESCRIPTION
A pair of very well-formed, sharp, semi-lustrous, soft metallic grey tabular blades of Bournonite are intergrown to create this attractive specimen. And the size of the crystals is spectacular - over 60mm tall! Viboras is a small, but still active silver-mine, which sometimes bring out small numbers of exceptional minerals like these outstanding Bournonite crystals - this one is from the most relevant discovery in 2007, most crystals were around 3 to 4cm, the dimension of the particular specimen is exceptional!
