This cabinet-sized specimen consists of a formation of fishtail selenite, a variety of Gypsum. The material is in fair to good condition, as it shows considerable visible damage in the form of scuffs and small cleavage areas. Its monoclinic form is excellent, however, showing a complex array of flat faces and straight edges. As is with most selenite specimens, this material is colorless, transparent and dimly to moderately clear, and has a pearly luster.
