Green Heulandite (#1134) Scolecite Las Choyas geodes formed millionsApproximate Size: 2. 25 inches Green Heulandite mineral specimen. Location: Aurangabad Maharashtra, India. Facts: Heulandite has a sheet like open framework structure, classified as a tectosilicate, where it's structure is composed of interconnected six membered rings of silicate tetrahedra, creating channels within the crystal that allow it to act as a Zeolite, capable of exchanging cation like sodium, calcium, and potassium within its structure.
