This cabinet piece consists of at least 5 intersecting Gypsum crystals. These crystals are generally in very good condition, showing no fresh breakage, and three of them even show definable terminations; two of these are completely intact. The longest one reaches about 2" (5 cm) in length. All show very good monoclinic prismatic form and have the standard pearly to vitreous luster of their specie. The crystals contain what appears to be a large quantity of included goethite or hematite, as their color ranges from rust-red to a deep brown. Their outer surfaces consist of a thin skin of clear selenite, however. At first I thought that they were epimorphs, but the physical properties of the Gypsum obviously extend completely through them.
