This small and simple specimen consists of part of a crust of reniform Hematite, commonly known as "kidney ore". Each of its rounded, intergrown nodules is made up of countless fibrous needles that do not exceed 0.3" (8 mm) in length, and are easily visible on the sides of the crust; these crystals are so compact as to be essentially intergrown into a massive form. The crusts outer surface has been polished to take advantage of the Hematite's bright, nearly metallic luster. It has a dark gray coloration and shows small areas of rust-red color and matte luster in the crevices where the nodules intersect and on the inner surface of the crust.
