A cluster of round Kidwellite nodules rests on one side of this cabinet specimen. These clusters reach diameters of 0.5" (1.3 cm) or more, but all of them are broken and incomplete. This breakage allows one to see the compact, acicular and radiating habits of their crystals, which are too fine and tightly arranged for effective study. All have a dull brown-green color and a dull silky luster. Some of these clusters contain limonite in their cores. All rest on a base of botryoidal hematite.
