This hand specimen consists of a thick, heavy crust that is made up of hundreds of partly intergrown Celestite crystals. The crystals on the more exposed convex side of the specimen are mostly damaged or broken, but those on the more sheltered, concave side are generally in excellent condition. All have excellent orthorhombic prismatic form, with well-defined edges and clean, flat faces that possess a vitreous luster. All of the crystals have the standard pale gray-blue coloration of Celestite, with the color's depth corresponding to the size of the crystals- a few of the smallest crystals appear almost colorless. All are transparent and incredibly clear in the upper halves of their lengths, except when marred by internal fracturing, but very few of the crystals have these. There is a small amount of a crumbly, dull tan host rock present.
