Large Cabinet, 21.3 x 11.0 x 9.0 cm
Machacamarca Mine, Machacamarca, ColaviSaavedra Province, Potosi Dept., Bolivia
A HUGE, 20-pound specimen of solid bournonite crystals to 3 inches, just stacked one atop the other! This find from December 2013 is the largest and finest (overall) really big example I have seen from the recent production at this mine. In person, it shines from all the shallow grooves along the crystal faces, which make it look more lustrous and "machine-like." Joe Budd photos.
