This is a cluster of two twinned, highly lustrous to splendent, black, cassiterite crystals, each measuring about 3.0 cm in length. It also appears to be a near floater. There are a couple of wilbers which do not diminish the quality of the specimen. Very old classic, out of the collection of noted Colorado collector EM Gunnell.
