A hard to find "cogwheel"-esque group of sharp, fairly thick, blocky modified twinned crystals of Bournonite with excellent luster and aesthetics. The piece would be classified as a large thumbnail / small toenail, and displays well from several angles (my favorite being the last picture). The stacked appearance of the crystals, combined with the bright metallic luster makes this one of the more unique smaller Bournonites I have handled from this mine. Excellent condition on the display side.
