Large crystallized copper specimens from the 1800s, in good condition, are treasured when they come to market. This huge knob of interconnected crystals is a large survivor of the glory days of copper mining in the Michigan Copper District and presents an unusual style of crystallization that results in a dramatic display with a good center of view, whereas most coppers are rather jumbly in comparison. This finely-patinated natural copper crystal formation comes with great history. The Quincy mine opened in the mid-1800s, and per the accompanying label, this dense specimen was found around 1890 and formerly held a position in the famed Seaman Museum, which specializes in the copper-mining history of Michigan. From the Wolfgang E. Henkel collection (with his label indicating prior origins), 1137 grams.
