MRR69CD4: Very sharp skeletal crystal with very marked spinel-law twinning, with well-developed faces and edges and of considerable dimensions for the locality. More reddish in color than usual for native coppers.
The locality was very prolific in its time, but more recently nothing comes from there anymore, and only old specimens like this one are available.
