This hand specimen contains scores of intergrown Celestite crystals. These crystals reach dimensions of 1.2 x 0.8 x 0.8" (3 x 2 x 2 cm) and are generally in good condition, though many are damaged or broken. All have excellent orthorhombic prismatic form, with well-defined edges and clean faces that possess a vitreous luster. The larger crystals tend to be somewhat cloudy and have a slightly deeper gray-blue color than the smaller crystals, which tend to be much clearer. Though there is a substantial amount of the pale brown, chalky host rock present, it makes up only a small percentage of the mass of the piece.
