An excellent, historic old-timer from the Phonenixville District, Pennsylvania. The sculptural and hefty gossan matrix has multiple vugs lined with lustrous, glassy, butterscotch-colored wulfenite prisms to 7 mm associated with pastel-green mimetite botryoids. The Phoenixville mines reached their highest production in the 1850s and the district was extinct by 1870. Specimens of this richness and quality are uncommon. Ex. PhiladeIphia Academy of Sciences Collection.
