System:TrigonalColour:Light blue, gray-white, ...
Hardness:4 - 5
Member of:Crandallite Subgroup > Alunite Supergroup
Name:From the Latin "plumbum" for lead, and "gummi" for gum, in allusion to its lead content and appearance at times as drops or coatings of gum.


Alunite Supergroup, Crandallite Subgroup. The lead analogue of Crandallite and Goyazite, and the phosphate analogue of Philipsbornite.
Compare also the chemically similar hinsdalite.

A secondary lead phosphate mineral.
