Several small patches of fibrous Shattuckite rest on the brown siliceous base of this cabinet specimen. The Shattuckite shows some fibrous, radial habit and a moderately deep blue color, but most of the patches are badly crushed or decayed, showing a paler blue. All have a dull luster. Surrounding the Shattuckite are larger patches of massive bisbeeite (a variety of chrysocolla) and ajoite. I cannot tell these two minerals from each other on this specimen, however.
