A few clusters of intersecting Kottigite crystals rest on the limonite base of this hand specimen. These crystals are in fair condition, showing some considerable damage, and do not exceed 0.1" (3 mm) in length. Where intact, they appear to have very good monoclinic bladed form. All have a dark gray/green/blue coloration and a rather dull pearly luster.
