A beautifully crystallized native copper specimen from Michigan. This is an excellent condition all around. The specimen comes with several previous labels from the A. E. Seaman Mineral Museum of Michigan Tech as shown at the end of the video. It is possible that the specimen came from the collection of an early curator at the Museum, one Jean Petermann Kemp. Prior to her, from the famous collection of John T. Reeder.
