Suolunite is a rare hydrated calcium silicate known from only a few worldwide localities. This particular botryoidal specimen is lustrous with a pastel purple color. It comes from ONE single pocket that was found here, an aberration apparently. The pocket was sold as purple prehnite to dealer Charlie Key, who in turn sold the whole lot to the Royal Ontario Museum. Any specimens such as this were deaccessioned from the museum in an exchange through dealer Rod and Helen Tyson, back in the late 1990s-I know, because I got many at the time but it has been a decade or more since.
