Interesting Facts
Pyromorphite is a rare lead chlorophosphate mineral that forms in the oxidized zones of lead ore deposits. Its characteristic hopper growth, where the edges of the crystals develop faster than the center, creates its striking skeletal formations. The Bunker Hill Mine, once a major lead and silver producer, is now celebrated for its world-class pyromorphite specimens.
