This large hand specimen consists of a formation of Fishtail Selenite, as the general outline and patterns on such pieces often resemble the tails of fish. The specimen is in moderately good condition, as it shows many spots of minor damage and a few spots of moderate but more severe damage. Its form is complex and appears to be very good, with well-defined edges and faces that show intense patterning due to growth and intergrowth of the crystals growing off of the twinning plane. It is colorless, has a pearly luster, and is transparent, though its clarity ranges from high to dim as one approaches the twinning plane from either side. There is no host rock present.
