Manandonite is a lithium-rich Kaolinite-Serpentinite Group mineral which despite having been discovered over a century ago is known only from two or three sites in Madagascar. This miniature specimen is from the Type Locality: Antandrokomby pegmatite. It features classic small spheroidal aggregates of finely crystallized platy Manandonite partially coating Feldspar. This rich miniature is from the amazing systematic collection assembled by the brothers Martin and Michael Günther (1951-2007 & 1956-2021).
