This is a cluster of lustrous and translucent, light apple-green prehnite fingers to 3.2 cm in length. At the top of the specimen are lustrous and translucent, colorless calcite crystals - the largest being 4.5 cm in length, with a few sidecars next to it. This large calcite is also doubly-terminated. Very nice association piece, with great balance! The prehnite stalactite atop perfectly balances the calcite next to it, for display, on this well-trimmed specimen
