Corundum

Item Description

How often does once have the chance to purchase a Montana Corundum (Sapphire) crystal? This is not a flat / compressed "disc" either, bur rather a robust, prismatic hexagonal crystal. Granted, it's not gem quality or brightly colored, but it does have a blue-grey hue on the exterior, making it desirable for any collector of thumbnails, especially U.S. thumbnails, or simply Corundum crystals.
