Large Chalcocite Crystal
This textbook crystal is one the most robust crystal by far from this locality, with a sharp, fat wedge-shaped form, and complete terminations on all sides. It is also a floater crystal. The bottom is microcrystallized, and so this is literally complete all around. This is a world-class Chalcocite.
