A rather nondescript-looking specimen, this piece consists of a pale-brown host rock that has patches and thin veins of Coconinoite, a rather rare uranium-bearing phosphate mineral, running through it. The Coconinoite exhibits no crystal form or habits. It has a pale-yellow color, a dull, matte luster, and is opaque. It does not glow appreciably under either short- or long-wave UV light, but there are some tiny spots that do, which probably consist of other uranium minerals.
