This specimen is largely covered with a druze of tiny prismatic tarbuttite crystals. These are colorless, and show excellent luster and form. There are other minerals present - the host rock is composed of limonite and possibly goethite, and there are scattered radial sprays of find milky crystals which I have not identified.
