This thumbnail piece consists mostly of botryoidal Dufrenite. The material has either a deep brown or a pale rusty-brown coloration depending on its level of oxidation, and its luster likewise ranges from silky to dull and earthy according to oxidation. Though no triclinic crystals are evident, it does show its classic botryoidal formation and some integral layering. There does not appear to be any base or host material present.
