PLUMBOGUMMITE SPECIMENS

Plumbogummite is a rare lead aluminum phosphate mineral that forms in the oxidation zones of lead ore deposits, often growing into smooth botryoidal and kidney-shaped masses. A member of the crandallite group, it’s a mineralogical look-alike that often requires lab testing to identify, adding to its intrigue for collectors. Mineral enthusiasts prize it for its unique chemistry and its frequent association with minerals like mimetite, pyromorphite, and galena in striking composite specimens.
