specimen number:
3011003

location:
Berkeley pit, Butte District, Silver Bow Co., Montana, USA

description:

Nice large classic combination piece with crystallized iridescent bournonite fairly rich throughout the top of this 13.5 x 9.0 x 7.0 cm quartz crystal coated matrix. Crystals of pyrite measuring to 0.7 cm present as well. Light chipping present to some of the lesser pyrite crystals, I think this in good condition. The piece will sit nicely by itself for display.
