This somewhat gemmy, translucent crystal is exceptional because you seldom see LARGER ettringites of this size that have such gemminess and retain sharp form, with luster as well. I've seen many brown ones, few yellow ones. It is complete all around and pristine save for the fact that (perhaps in heat shock) it perfectly cleaved down the middle in transport home form Charlie Key's, and so what once was a $7500 specimen is now reduced to $1500 to ensure it sells and gets away from me because it is depressing. but it really LOOKS like a pricier rock and displays dramatically. I had it shot at the worst possible angle here to catch the join head-on. In person, the repair is really NOT obvious at all, and this remains a significant, rare, and beautiful specimen.
