This powellite specimen is an incomplete crystal, showing only two good crystal faces, one side that looks like a cleavage plane, and the remaining surfaces, while not looking like damage, they are not flat crystal faces but rather have an irregular surface where the growth pattern was likely interrupted by something in the way. This specimen glows a pretty yellow color under shortwave ultraviolet. The powellite is transparent, but has so many internal fractures as to appear only translucent.
