This large specimen is similar to the specimen GYP-23 in that it consists of a single, large crystal that contains a noticeable phantom. It shows excellent monoclinic prismatic form with an almost rectangular cross-section, and appears to be twinned. Its termianation is complex and consists of at least 2 different, intergrown crystal terminations. Its edges are well-defined ,and its faces are striated but clean and show a bright, vitreous luster. The crystal is colorless, transparent, and moderately clear, as it contains many internal fractures and inclusions. Though only partially visible, several of these inclusions consist of moving air bubbles that denote two-phase inclusions! The crystal is also clear enough for one to see the subtle but visible phantom that is probably made of countless tiny hematite inclusions. Again, the phantom's termination seems to match that of the crystal itself. However, it is not very easy to study, as there is a large cavity in that area of the crystal that was caused by the separation of another crystal that was partially intergrown with this one.
