A very beautiful specimen! I must confess, even though I consider myself a fluorite collector with some knowledge, that I never heard of that locality before. Maybe because my general knowledge about Argentinean minerals is nearly zero :-/

Both your last specimens are simply incredible! And I agree with Philippe concerning the rhodo: Really good rhodochrosites are hard to get, no matter from what locality. And having several (!) Oppu Mine (!) rhodos in such good quality must be a pleasure, you are really lucky to own such pieces :-)
