Mordenite Value, Price, and Jewelry Information
Compact, fibrous material is cabbed because the fibers provide a chatoyancy that sometimes yields weak catseyes. Coloration in the material is due to staining. This is a relatively unexciting mineral, and gems are equally uninspiring. Nevertheless, it has been reported as being cut for collectors.
Occurrence: In veins and cavities in igneous rocks; also forms as hydration product of natural glasses.
