This rather odd specimen contains two small clusters of warped, apparently incomplete Creedites. They are in excellent condition, showing no fresh damage, and do not exceed 0.2-0.3" (5-8 mm) in length. All have highly warped, nearly unrecognizable monoclinic prismatic form that appears to have been caused by intense erosion, probably by water. They are essentially colorless, show a pearly luster, and are transparent and quite clear. They are rather difficult to isolate amid scores of what appear to be selenite blades. The Creedites glow violet under shortwave ultraviolet light, however. These blades look very much like selenite, including having a rhombic cross-section, but they are too hard. This made me consider barite, but the form does not seem to correspond to the orthorhombic form of barite. All are transparent, quite clear and tend to be colorless, but many have rusty inclusions. Their luster is bright and vitreous, and their prism faces show little striation.
