Natrolite
Puy de la Piquette, Veyre-Monton, Clermont-Ferrand, Puy-de-Dôme, Auvergne-Rhône-Alpes, France
Sprays of colorless prismatic natrolite crystals to 2.7 cm in length are set nicely upon a 7.4 x 7.0 x 3.7 cm matrix. Some damage is present as seen in the photos, still quite nice for the species/locality. Ex Steve Pullman collection with a previous label from Richard Barstow.
