- Prehnite Cast After Anhydrite
- Small Cabinet, 7.6 x 4.0 x 3.0 cm
- Prospect Park Quarry, Prospect Park, Passaic Co., New Jersey, USA
A single spire over 7 cm in length that is very lustrous, and translucent with a light apple-green color, is the highlight of this prehnite. The bottom face clearly exhibits a window into the hollow cast of what was once a large anhydrite crystal. Unusual style for the pocket.
