Calcite with Quartz casts after Anhydrite

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 a sharp, lustrous, gemmy, golden rhombs of Calcite with an attractive "spire" of Quartz forming a cast after preexisting Anydrite on Quartz on matrix. You can see some exposed areas on the side 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.
