This large specimen consists of a single, twinned Selenite crystal with a flat base cut into one end. It is in good condition, showing a few spots of only light damage, and it has good monoclinic prismatic form, with well-defined edges and clean faces that show subtle, complex patterns in certain areas. Its termination is very uneven, but one can still trace the twinning plane across it by sight. It is colorless, transparent, and moderately clear, containing a few planes in which muddy brown inclusions are trapped. A few small patches of this material are visible on the outside of the piece, but there is no actual host rock present. The piece stands up with moderate stability on its cut face. Such pieces are sometimes placed on a lighted base to form a decorative "lamp".
