We had two of these amazing limonite specimens in auctions awhile back. We spent 4 months after that trying to track down the Chinese guy who had them, and by the time the Tucson Show rolled around, we had found him and arranged to meet him in Tucson. There, he had about 65 specimens - the great majority of which were ugly, but some of which had the amazing iridescence you see here. We had to buy the entire lot of 65 to get the good ones - which was hard to bite off, but we did it. This is a mini, with perhaps a little more of the rusty parts showing than some other pieces (remember that limonite is iron oxide; all of these specimens have spots of "rust" showing but they blend in with the colors as you can see). It DOES have the amazing play of colors that makes these so notable. Note that we did not see ANY MORE of this material at the show, with anybody! 5.2 x 4.2 x 2.6cm
