This is a beautiful specimen, displaying a large, round cluster of epistilbite in a cavity of the host rock. The individual crystals are colorless and transparent, and have a diamond-shaped cross section with roof terminations. They are neatly organized into a (partial) spherical cluster that appears white due to the interaction of the individual crystals. This cluster rests on a crust of a very dark greenish-black mineral, organized as tiny balls with a radial growth pattern. Under a loupe, it reminds me of some barite or selenite balls, or of hematite, but I do not believe it is any of these, given its origin. If you recognize it, please let me know! There are two other spots on the specimen with exposed epistilbite and this green-black mineral, but these areas are incomplete.
