This area of the upper peninsula of Michigan has produced not only the most, but, overall, the finest copper specimens in the world. While not large, this copper specimen does have the quality that one looks for. A stalk of copper crystals give way to two, euhedral, lustrous, doubly terminated, patina rich, copper crystals, to 2.5 cm across. They have a very unusual form, almost like a flattened pyramid, that makes this piece stand out visually in a case even amongst larger coppers. The eye goes right to those weird crystals which, I admit, at first look fakey but are not!
