Exceptional pseudomorph of Mottramite after dendritic Copper, of such elegance that the pics say it all. There is one weak bit in the middle that has been stabilized with a small dot of glue in the past (i.e. It could be repaired, as well). Now, the piece can be left as is, which I think is best for the sheer drama, or clipped at the stabilization spot in the middle and turned into two phenomenal and unique thumbnails....either way, a killer! Purchased from the Zweibels in 1976
