Millerite from Wisconsin is one of the rarest USA classic metallic species, and I tend to buy every one I see for sale, just to have them. They are unobtainable except in old collections. This specimen features a protected spray of crystals, 2.5 cm tall, sitting in a vug in the matrix. It would be considered a largeish specimen for the material, and unlike most it actually makes for a good display piece with the crystal cluster atop.
