A magnificent, very arboreal-looking cluster of THICK copper crystals, forming a solid tree rising from the quartz matrix. This is a dramatic and exceptional piece with a lot of character, and is MUCH MUCH better in person than it appears. It came to me in trade with Gene Meieran, in whose collection it resided after he made a trade with the Seaman Museum. Courtesy of curator George Robinson, I can say that the piece came to the museum "some time after 1917." Hubbard died in 1933. There's general information on Hubbard given in the MR "copper country" issue in the section at the end on the Museum's various collections.
