At least 20 trigonal prismatic Smithsonite crystals rest in the dull brown, semicrytalline matrix of this hand specimen. These crystals reach a maximum length of 0.5" (1.3 cm) and are in moderately good condition, as several are damaged or broken. Those that are intact, however, have excellent form, with well-defined edges and clean faces- a few possess second terminations that are incomplete due to intergrowth with the matrix. All have a pale pink coloration and a dull pearly luster, and are dimly transparent due to cloudy inclusions and internal fractures. The matrix in which they rest appears to be made of countless tiny, intergrown crystals of what is most likely more Smithsonite, as it effervesces in concentrated hydrochloric acid, though much more slowly than calcite would.
