This large, 3-dimensional prehnite specimen is highlighted by a very lustrous and translucent, light apple-green finger that rises 5 cm in height. Additionally, there are several calcite crystals to 1.5 cm in length that are lustrous, translucent and colorless. On the bottom face is evidence of hollow casts that once were anhydrite crystals upon which the prehnite casted over. Pristine, save only for very minor wear at the base, this is one of the relatively few fine larger pieces.
