Well formed bi-colored green Tourmaline exposed on matrix from THE classic US locale for Elbaites, Mt. Mica. Collected in the sixties by Les Hitchings, the large Elbaite is in perfect condition. The Matrix is a typical mix of Quartz crystals with Cooketite and feldspar with several partial Elbaites and one small Tourmaline is still fully encased in the Cookeite and could be exposed if so desired. Since 1821 this locality has been the most famed US Gem pegmatite.
