The famous Prospect Park Quarry is one of the most impressive zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. This specimen features rare blue-grey altered crystals of babingtonite which are associated with honey-colored Stilbite aggregates, pale golden Heulandite crystals and Calcite rhombohedra on Quartz. The Babingtonites from this locality are very distinctive, and certainly some of the most attractive for the species from the standpoint of the unusual color. Unfortunately, this great New Jersey locality is being filled in for a housing development (like so many of the great Trap Rock localities in this area), and pieces like this one will be never be collected again. A wonderful full-size cabinet display specimen of this hard-to-find material. Ex. Richard Kosnar Collection.
