location:
Copper Falls Mine, Keweenaw Co., Michigan, USA
description: Incredibly aesthetic and very choice crystallized native copper specimen, this including one rather large sharp crystal measuring almost 4.0 cm in one direction. Very little attached matrix. Checking the backside of the specimen there are negative impressions of what were once analcime crystals now gone. In terrific condition. Superb classic old time Michigan specimen.
