This traprock locality is one of the most impressive Zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. This particular specimen is an attractive piece consisting of gemmy, beautiful, lustrous apple-green spheres of Prehnite with minor Calcite rhombohedra on the reverse side of the piece. The largest Prehnite "sphere" measures 1.7 cm across. A very attractive specimen of this classic material. It must be noted that Prospect Park will never produce these specimens again in a very short period of time. The quarry is currently being backfilled to make room for housing developments, and will soon be nothing more than a memory. Ex. Brian Kosnar Collection.
