Perhaps the world's largest fine Neptunite crystal in this quality? It certainly is the largest I know of, with form and terminations. In fact, it is a doubly-terminated floater! From the famous benitoite deposit in California that also produced earth's finest benitoite crystals and is now nearly mined to exhaustion, it is a certainty that nothing like this will ever be found there again. Ex. Larry Conklin collection, exchanged out many years ago before he passed away, to Bill Larson, from whom I obtained it in trade. Larry's old private collection label accompanies this, and it would have been in his secret stash of USA classics in this size range, which he kept for many years. A monumental and important US mineral specimen, this is also considered the best locality for the species in the world, as a bonus.
