Cabinet, 15.0 x 11.0 x 7.0 cm
This Trap Rock locality 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 particular specimen is a great, large "dual layered" specimen consisting of soft, light green, spheres of Prehnite sitting below a layer of sparkling, gem quality, yellowish green, highly lustrous crystals of Datolite on basalt. A great large cabinet from this historic locality. 15.0 x 11.0 x 7.0cm
