Well crystallized branching grouping of native copper with small crystals of analcime. This is in good condition and shows a nice tenorite coating in one area. Interesting with the analcime association. The specimen comes with a previous label from the A. E. Seaman Mineral Museum of Michigan Tech collection as seen at the end of the video.
