A supremely sharp, jet-black, metallic twinned crystal of ferberite from perhaps the best locality for the species in its twinned habit. This crystal is 3-dimensional, SHARP, and really quite breath-taking for a "black ugly." It is as close as you could ask to pristine, with just a few really insignificant dings and otherwise compete all around. It was one of the finest pieces, certainly among the best few miniatures, in a small pocket recovered in about 2004-2005 and sold by the dealership of Bolivian mineral specialist, Brian Kosnar, to a good mutual customer. Since that time, no more of this quality have been found
