The Worlds Largest Copper Crystal

Believed to be the Worlds Largest Native Copper Crystal, this 11.4 Cm (4.5 in ) Dodecahedron was found in August of 1991 by Joe Ziolkowski at Point Prospect near the tip of the Keweenaw Pensinsula of Michigan's Upper Peninsula.

Joe has agreed to write a report on his experience and it will be posted here as soon as I receive it.
