Though there are perhaps hundreds of Celestite crystals on this specimen, only one of these is both intact and larger than 0.1 x 0.1 x 0.1" (3 x 3 x 3 mm). This lone crystal has dimensions of 0.4 x 0.4 x 0.3" (1.0 x 1.0 x 0.8 cm), and is in excellent condition, showing no damage. Its orthorhombic prismatic form is also excellent, with well-defined edges and clean faces that possess a pearly luster. It has the standard pale gray-blue coloration of Celestite and is transparent and quite clear, though it contains several internal fractures. Several equally large, broken crystals rest nearby, and countless tiny Celestites create a druse that coats part of the pale brown host rock, which appears to be made of shale.
