Detailed Description

A complex group of sharp, twinned bournonite crystals. These crystals show the "cogwheel" twinning habit. The prism faces on these crystals are brilliantly lustrous with many complex steps. Up close it looks a bit like a machined landscape - very cool. On the back and the bottom, the piece shows recrystallized surfaces. In excellent condition (tiny nicks on the piece if you search for them, two at the very outer periphery). This is a stunning bournonite.
