Scores of long, thin orthorhombic prismatic Celestite crystals make up the bulk of the mass of this hand specimen. The largest of these crystals is obvious (see the close-up image), and has dimensions of 1.9 x 0.5 x 0.4" (4.8 x 1.3 x 1.0 cm)- all of the other crystals are much smaller, and generally do not exceed 1" (2.5 cm) in length or 0.1" (3 mm) in width or depth. Though many of the smaller crystals are damaged or broken, a surprisingly large number are intact. All have good form, with well-defined edges and clean faces that possess a bright vitreous luster. They have the classic pale gray-blue coloration whose depth corresponds to crystal size; thus, some of the smallest crystals are essentially colorless. They are all transparent and quite clear, though the largest crystals tend to cloud quickly towards their bases. A thin crust of a crumbly brown host rock covers the underside of the piece.
