Several botryoidal crusts of compact, radial Wavellite clusters rest on the gray limestone host of this cabinet piece. Though many of these crusts appear to be separate, I believe that all intersect each other at various points. The largest crust is in excellent condition and is normally about 0.2-0.3" (5-8 mm) thick. Each crust is made up of many round, intergrown nodules which are in turn made up of countless tiny, compact, radiating Wavellite needles. The surface of each crust has a deep green color and a bright, silky luster; their cross-sections show a paler green color and a pearly luster. I believe that some of the crusts have been covered by the gray limestone.
