Stilbite with Datolite on a cast after Anhydrite (ex Richard Kosnar Collection)

Item Description

The famous Prospect Park Quarry 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 specimen features caramel colored "sheaf"-like crystals of Stilbite in a radial burst. The underside of the specimen shows a few rich green color crystals of Datolite (which measure up to 1.3 cm) and a hollow striated cast that formed after preexisting Anhydrite. A nice association specimen and a good representation of this wonderful phenomenon that existed at Prospect Park. Sadly, 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.
