I admit that I have never seen another of these but I am told that this is a relatively well-formed, sharp crystal. It is 4 mm tall, and embedded partially in matrix. This specimen was in the collection of Clarence Bement, and then sold to JP Morgan who donated it to the American Museum of Natural History. Generally, Bement was surprisingly active in his pursuite of great rarities! (TYPE LOCALITY)
