An excellent, historic, old-timer from the Phoenixville District, Pennsylvania. Tiny, lustrous, olive-green, pyromorphite prisms cover the gossan matrix. The pyromorphite is richly sprinkled and complimented with brick-red wulfenite crystals to 2 mm - very large and rare for the locale. The Phoenixville mines reached their highest production in the 1850s and the district was extinct by 1870. Specimens of this combination or richness and quality are uncommon. Ex. Robert Whitmore Collection.
