This thumbnail specimen consists of scores of tiny tabular Calaverite crystals that concentrate around and inside of hollows in the feldspar host rock. These crystals do not exceed 0.1" (3 mm) in any dimension, and most are broken or incomplete. Where intact, their monoclinic form is good, with sharp edges and striated but clean faces that possess a bright metallic luster. Their color is a bright silvery white, and the material is easily visible against the often dark-brown patches on which they rest. Most of the host rock, however, has a pink-orange or pale gray coloration and a pearly luster.
