Manandonite is a chlorite-serpentine type mineral containing lithium and aluminum. Lacroix (1912) named the mineral for the Manandona River, near the original occurrence. For some time, the mineral was believed to be a variety of cookeite (MAC Short Course on Granitic Pegmatites), but later study showed the mineral to have a distinct unit cell and composition (Ranorosa et al. 1989). Zheng and Bailey (1995) solved the crystal structure and established a definite formula for the mineral. Manandonite forms rounded micaceous aggregates to 3 mm across with 2 mm white quartz crystals on this piece.

This specimen was part of the personal collection of Ralph Merrill, proprietor of the prolific mail order business Minerals Unlimited. Merrill obtained this specimen in 1952 from Burminco (label included). Merrill's collection card and label also ship with the specimen.
