An exceptionally rich example of a very rare manganese phosphate, that I personally had never even seen. However, I am told by those who know more than I do, that this is a very impressive piece, the best seen on the market certainly and better than a few major private holdings have (one source told me, after thinking about museum holdings he had seen, this may be the richest specimen known). The crystallization is both rich and frankly aesthetic, all things considered. It is on the front and the back. From what research I could do, the locality seems to have not yet been publicly reported to produce this species, although with the old Smithsonian label, I would tend to believe it. Its hard to make this stuff up....and there would have simply been no motive at the time. Exchanged from the Smithsonian to the Academy in the 1920s.
