This traprock locality is one of the most impressive Zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. One of the unique aspects of Prospect Park is the fact that the basalt didn't form in "pillow lavas" like those at the New Street Quarry. This particular specimen is an attractive piece consisting of beautiful, gemmy, rich green color spheres of Prehnite sitting atop a layer of basalt. The largest sphere measures 2.1 cm across. A great miniature from this historic locality. Ex. Brian Kosnar Collection.
