We had two of these amazing limonite specimens in auctions awhile back. But that was all we had. 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 about 6 or 7 of which had the amazing irridescence you see here. We had to buy the entire lot of 65 to get the 6 or so good ones - which was hard to bite off, but we did it. So here you have it: one of the most amazing looking rocks you would ever want to see! IT IS MUCH MORE COLORFUL AND FLASHY In PERSON - just very hard to capture in pics. It shimmers with an amazing spectral array of colors that look almost unreal! This is not only a large one, but is an actual STALACTITE, complete and undamaged all around! Note that we did not see ANY MORE of this material at the show, with anybody! 13.5 x 4.7 x 3.9cm
