Several pseudo-rhombohedral Barite crystals are embedded in the creamy-white host rock of this specimen. These crystals reach visible dimensions of 0.8 x 0.5 x 0.4" (2.0 x 1.2 x 1.0 cm) and are in moderately good condition, showing light but widespread damage. All have excellent form, with well-defined edges and clean faces, and a few appear to show the "hopper effect" on one or two faces. They are a moderate golden-brown in color and translucent to dimly transparent, and have a dull, waxy luster. The pale base rock on which they rest actually resembles concrete, in a way.
