This cabinet specimen consists of scores of Celestite prisms that rest in calcite-lined hollows in a shale host rock. These crystals reach lengths of nearly 0.4" (9 mm) and are generally in excellent condition due to the protective nature of their surroundings. All have excellent orthorhombic prismatic form that is capped by a basal pinacoid and the standard pale blue-gray color and pearly luster. All are translucent and cloudy. The calcite crusts on which they rest are each made up of hundreds of tiny crystals.
