This is a very 3-dimensionalcluster of very lustrous and translucent, light apple-green fingers of prehnite, to 4 cm in length. Evidence exists on the bottom of their formation as casts epimorphs- you can see the hollow casts after anhydrite that they coated and replaced. Very nice display piece for the size, and complete all around, this looks good either horizontally OR vertically and has a lot of display options.
