Ramsdellite is a rare manganese oxide. This is a showy intergrown plate of equant, splendent, black ramsdellite crystals to 7 mm across, which is large for this new find. Ramsdellite from this small and defunct mine in a remote corner of Arizona was first found, I am told, in the early 1900s. However, the locality was apparently lost for some time and only rediscovered by the father/son team of Roy Jones and Dick Jones in the 1960s. Some of this material came out then (Roy says about 6 flats). This recent find appeared literally in the middle of the Tucson show. It features very fine quality Ramsdellite crystals on manganese-rich matrix, and the crystals have excellent luster and jet-black color to them.
