Plumbogummite after pyromorphite and galena, Beauvoir, Echassières, Allier.


Very nice sample showing complex mineralogy including pseudomorphosis of pyromorphite “barrel” crystals to plumbogummite (also called lead-gum) and galena deadboxes. This one disappeared, leaving only the hollow shape of the initial cubic crystals, a little Pyromorphite having crystallized there. A little bit of galena is still sporadically visible at the base of the crystallization.
Provenance: Beauvoir, Echassières, Allier.
Plumbogummite was certified by analysis on this specimen.
