Fluorite

Dark purple Fluorite dominated by a larger octahedra with beveled edges. This is an old piece from an old, obscure Namibian locality. An unusual piece for a Fluorite collector. I found a couple interesting things about the locality in a Mindat discussion, as follows: 'This was like hunting a unicorn! Finally at least I saw a specimen - these are in the display of Narodni Museum, Prague, Czech Republic. These 2-3 cm Fluorite crystals are purplish black and show combination of cube and octahedron (left specimen) and cube, octahedraon and dodecahedron (right specimen). They come from Pforte in the Namib Desert, Namibia. I always heard of them, visiting Namibia, speaking to Fluorite collectors, etc., but nobody had a piece! Now I have seen one, regrettably the deposit is off-limits being in a natural reserve' and 'Pforte 37 east of Swakopmund. Dark-purple (to nearly black) octahedra, as excellent crystals, usually about 2cm on an edge but without matrix. Today this locality is in the Namib Naukluft Park and not accessable. The exact spot has probably been lost.'
