Description
Ramsdellite is a rare manganese oxide. This is an intergrown piece of equant, splendent, steel-gray Ramsdellite crystals to 5 mm across. Ramsdellite from this small and defunct mine in a remote corner of Arizona was first found, I am told, in the early 1900s. This specimen features very fine quality Ramsdellite crystals on manganese-rich matrix, and the crystals have excellent luster and wonderful striation to them.
