Item Description

Sharp cogwheels of gunmetal-gray Bournonite crystals are sprinkled among "drusy" groups of Sphalerite along with brass colored Chalcopyrite and white Quartz on matrix from Pachapaqui. The largest Bournonite group measures 1.1 cm. Very good quality, and beautiful to view up close. I can't really see any damage of note. A wonderful, eye-catching cabinet sized display specimen from this famous locality in Peru.
