About Plumbogummite
Plumbogummite is a fascinating secondary lead aluminum phosphate mineral that forms in the oxidation zones of lead ore deposits, where minerals like galena slowly break down and recombine with phosphate-rich groundwater. Known for its sculptural botryoidal and reniform masses, it often shows a soft resinous glow despite its typically earthy appearance. Its name reflects this dual personality—plumbo for lead and gummite, a historic term for gum-like secondary lead minerals. Part of the crandallite group, plumbogummite is a notorious mineralogical look-alike, often requiring lab testing to distinguish it from relatives like crandallite or florencite.
Collectors prize plumbogummite for its unique chemistry and its frequent role as the “canvas” in composite specimens, where brighter minerals such as mimetite or pyromorphite form sparkling islands atop its rounded nodules. It commonly occurs with mimetite, pyromorphite, galena, goethite, cerussite, and limonite. Notable sources for fine specimens include China, Australia, Germany, France, England, and the United States, though quality pieces remain relatively uncommon on the market.
