This trap-rock locality is one of the most impressive Zeolite localities in the world. This quarry has produced some amazing specimens in the last 100 years. This piece is an attractive specimen consisting of a vug lined with translucent, water-green spheres of Prehnite which are associated with a modified grey-white Calcite rhombohedron at the top most part of the specimen. The largest Prehnite sphere measures 9 mm across, and the large Calcite crystal, though cleaved on the end, measures 3.7 cm across. A fine cabinet specimen from this historic locality.
