RM1650   Ramsdellite

Mistake mine, Sam Powell Peak, Box Canyon, Yavapai Co., Arizona, United States

Very rich ramsdellite specimen, a rare manganese oxide, formed by several interpenetrated and some isolated groups of well defined crystals. Brilliance is really notable and on matrix. Ramsdellite from this small and defunct mine in a remote corner of Arizona was first found, 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. These specimens are from a recent found in 2016.


Size: 6.5 x 5.5 x 3.0 cm.
Main crystal: 6 x 5 mm.
Found in 11/2016.
