This hand specimen consists of several radiating sprays of Anhydrite blades. These blades are generally in good condition, showing very little damage, and reach lengths of up to 4.8" (12.2 cm). Each cluster is made up of several intergrown Anhydrite blades that have excellent orthorhombic bladed form, with well-defined edges and clean faces that possess a pearly luster that appears nearly silky from some angles. All have the classic pale blue coloration with a hint of gray and are translucent. Tiny smatterings of colorful chalcopyrite are scattered on the crystals and a single cluster of small calcites is present, but there is no host rock.
