Interesting cluster of Ulexite pseudomorph after Borax. There is one 4 cm double terminated Borax crystal pseudomorphed to Ulexite. There are also several black spots on the surface that may be Arsenic since similar to a few other of these pseudos with black spots labeled as Arsenic. The sharp and form of this specimen is unique from all the other specimens of this pseudomorph that I had in Jim Minettes large Borate lot. ex Jim Minette collection |
