A very rich specimen chock-covered with a thick carpet of plumbogummite that completely carpets an earlier growth of mimetite, showing the partial alteration of the mimetite to plumbogummite. This is one of the largest intact specimens recovered, and is among our largest specimens. It is a phenomenally rich piece that has more plumbogummite on it than probably all other old English plumbogummite's in private collections, combined. This is a very rare mineral after all!
