Heulandite with Babingtonite on a cast after Anhydrite (2013 find)

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 many sharp, pearly, very lustrous, gemmy, pale pink, "curved" groups of Heulandite up to 1.0 cm associated with layered, rare blue-grey crystal groups of Babingtonite (partially altered to some kind of Pyroxene) measuring up to 5 mm sitting on a "fan"-shaped a cast after preexisting Anydrite. A tiny ball of Prehnite can be seen nestled amongst the Babingtonites and Heulandites. You can see some exposed areas on the back of the piece where a cast was opened showing the thin orthorhombic internal striations. 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. This piece was collected in 2013.
