natures velvet


this is an interesting sample of psilomalane, barium-manganese oxide hydroxide (Ba,H2O)2Mn5O10 most often it occurs in massive or botryoidal masses, this occurrence is a sample of the fibrous on botryoidal, the pic doesn't show that well, but the fibers are like the fibers of velvet. What's most odd is I found this sample for sale at a children's center in kansas city.




still experimenting with my new camera, I think I like its macro focus, still need to work on it some

The second photo is gorgeous. I found a wild sample of psilomelane that I shot for About.com. Your specimen looks expensive. Do you collect minerals?
