A super specimen with gem crystals, on matrix, from a surprising and small find of late 2005. These are the best seen in 20 years, of this rare gem species related to ettringite and sturmanite. This piece features a great balance with gemmy calcites overlookin gthe matrix loaded with thaumasites...And, they happen to be gorgeous! In person, there is more luster. I was able to get some of the cherrypick of the lot, when they were found, and all of these were selected for best quality gemminess and luster, as well as aesthetics.
