Ex. Ben Vone Collection 

Superb group of very well-f0rmed copper crystals with a perfect patina on a matrix of crystallized tan adularia and pale yellow calcite crystals from the Michigan Copper Country. No specific mine noted, but most likely from the southern part of the district in Ontonagon County. Great quality and wonderful display aesthetics. Comes with a custom acrylic display base.
