This cabinet piece consists of a galena crust that is coated with a crust made up of hundreds of intergrown Dolomite crystals. These crystals are generally in very good condition and reach diameters of 0.5" (1.3 cm). All have excellent rhombohedral form with slightly curved faces and edges, a white color and a dull pearly luster. Some are coated with a thin, dull, gray crust. The galena base is made up of countless tiny, intergrown cubes, and a considerable amount of crystalline pyrite is present.
