This hand specimen consists of a single hexagonal prismatic Apatite crystal that is in very good condition; the crystal shows almost no human-induced damage. Its form has a few highly unusual aspects, though- one of its terminations is malformed and quite odd. This termination is definitely pyramidal in shape (see the close-up image), though a few of its faces are rounded and spoiled due to the crystal's intergrowth with several books of mica and many albite blades. The termination is capped by a small basal face that has a hexagonal shape and a triangular hole extending about 0.5" (1.3 cm) down into it. The other termination is made up of a somewhat disheveled but regular basal termination into which are intergrown several small muscovite books. The crystal has an odd, pale gray-green coloration and a dull, waxy-to-matte luster. It is thoroughly opaque.
