Prehnite (gemmy) (ex Brian Kosnar Collection)

Item Description

This Trap Rock locality is one of the most impressive (and under appreciated) Zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. This particular specimen is an attractive display piece consisting of gemmy, beautiful, lustrous apple green color 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 display 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.
