A cluster of large and heavily intergrown Smoky Quartz crystals rest on the feldspar base of this cabinet specimen. Most of these crystals appear to be damaged to some degree, but most of the damage does not appear to be fresh. The largest crystal has visible dimensions of 3.4 x 3.1 x 1.7" (8.6 x 7.9 x 4.3 cm), and like all of the others, has well-defined but highly disseminated form- one could conceivably call it elestial, as all of the crystals have edges and faces that tend to form "sawtooth" patterns. Otherwise, each has well-defined edges and clean faces that possess a rather dull, pearly luster. They all have a very dark brown color that is nearly opaque. Their opacity is helped by the presence of many internal fractures, several of which reach their surfaces. The base material is almost definitely a feldspar, but th demarcation line between the feldspar and the Smoky Quartz is very difficult to determine due to a very gradual change in color and similar visual properties.
