Several crusts of green Smithsonite rest on the dull Smithsonite/goethite base of this hand specimen. The largest of these crusts is the most striking, as it has a beautiful, deep grass-green coloration and a bright, silky luster. The crust is no more than 0.1" (3 mm) thick and shows an excellent botryoidal habit. A few other green crusts and veins lie elsewhere in the host rock, but none have the intensity of color or luster that the large one has.
