Prehnite "finger casts" after Anhydrite

Item Description

During the latter half of 2010, one of the most momentous Prehnite discoveries was made at the Prospect Park Quarry. A large number of some of the finest quality Prehnite casts were collected in a series of pockets in the middle of the quarry in a dome-shaped structure measuring approximately 40 x 40 x 40 feet (approximately 12 x 12 x 12 meters) that is locally referred to as a diapir. This discovery stands as one of the most impressive and important discoveries, not only in recent years, but perhaps in the history of the Prospect Park Quarry. These specimens represented one of the very last discoveries at Prospect Park before the quarry was completely closed down. This piece is a wonderful large miniature / small cabinet sized display specimen with a pair of finger-shaped casts flaring out of the sides of the piece. The color is a pleasing light green, with decent gemminess and luster that is partially hindered by a slight coating of a secondary clay mineral. The piece is in great shape overall, and displays well from several angles. Worthwhile for the size and price.
