NEW FIND - RAMSDELLITE CRYSTALS from ARIZONA
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). I have seen it
turn up, from time to time, in old US collections. However, it has
remained fairly rare on the market, and thus expensive. This recent
find appeared literally in the middle of the Tucson show and surprised
me. It features very fine quality Ramsdellite crystals on
manganese-rich matrix, and the crystals have excellent lustre and
jet-black color to them. There was an old MR article about the Mistake
Mine in one of the Arizona issues, and also this is referenced in
Mineralogy of Arizonaby Bideaux, et al.

Crystals of equant, splendent, black ramsdellite reach .5 cm across.
On matrix is a plate of intergrown, equant, splendent, black, ramsdellite crystals, to .5 cm across.Some of the crystals are doubly terminated. Some matrix shows at bottom. Very robust, and 3-dimensional, this is much better in person and a greeat larger example for the price.
This plate of equant, black ramsdellite crystals, to .5 cm across is particularly splendent and fine. For a flat plate, in this size range, its the best one
A small amount of matrix is host to a plate of equant, splendent, black crystals of ramsdellite, to .5 cm across.
Emplaced on matrix, this plate of equant, splendent, black ramsdellite crystals, to .5 cm across is partially coated by a thin, white, mineral that may be gypsum. Superb example by previous standards, this is a very aesthetic specimen that in person really stands out.
Nearly covering its matrix is a plate of equant, splendent, black, ramsdellite crystals, to .6 cm across. One of the larger pieces, very 3-dimensional overall. Many crystals are quite isolated, which is unusual.
In a pleasing sculptural vug is a plate of equant, splendent, black, ramsdellite crystals, to .6 cm across. This is a superb example of the species, and a beautiful, 3-dimensional piece in person
A cluster of equant, splendent, black, ramsdellite crystals, to .5 cm across, is emplaced on a small amount of matrix. A few of the crystals are also doubly terminated. In addititon, there is a thin coating of what might be gypsum, on some of the crystals. Very 3-dimensional cluster atop!
Emplaced on matrix is an intergrown plate of equant, splendent, black, ramsdellite, in crystals to .5 cm across. One of the larger, more robust specimens, with good isolation of larger crystals upon smaller ones.
This is an aesthetic mound of intergrown, equant, splendent, black ramsdellite crystals, to .5 cm across.
Equant, splendent, black, ramsdellite crystals, to .5 cm across, totally cover this specimen.
Emplaced on matrix is a plate of equant, short prismatic, splendent , black crystals of ramsdellite, to .5 cm across. One of the larger pieces recovered, as they tended to fracture fairly readily into small plates. Also, this is more 3-dimensional, with backing matrix.
A vuggy matrix is covered with equant, splendent , black crystals, up to 6mm across. Large crystal size and unusual isolation of the large xls upon smaller ones make this a special piece.
This is a plate of intergrown, equant, splendent, black, crystals of ramsdellite, to .5 cm across.
The largest overall specimen I have, with a pocket in heavy ore. Nestled in a vug of massive ramsdellite, are equant, splendent, black crystals of the same species, reaching .5 cm across. Beautiful, large, display-sized example from this find with INCREDIBLE lustre for the species!
