This remarkable museum-sized specimen was the pride of the collection, and stands up there with the finest large copper specimens in any museum in the United States as a piece of US history. Even the Seaman Museum, our largest repository of historic and fine copper specimens, has not many pieces with such large cubic crystals and I think not another of this size for the style. This specimen has cubes all over it, a rare form in copper, to 2 cm. It has reticulated clusters of elongate, rectilinear crystals. It has distorted crystals of other habits. It has spinel twins tucked in the body. It is overall a riveting piece with so many different kinds of crystallization. Taking the size into account, as well, and you really do have a museum-grade, world-class copper. It was in a museum, in fact, for most of the 1900s - donated to Cranbrook at some point and then traded out by the late Neal Yedlin in the 1970s. I am told that this was the cornerstone of the Yedlin Collection, which was abosrbed into this collection on its purchase. Comes with a custom lucite display base. (probably Copper falls or Phoenix Mine),
