An aesthetic 2.2 x 2.0 x 2.0 cm specimen with a razor-sharp deep-blue 1.1 cm cube centered on matrix. Quite simply, one of the finest examples for the size as a thumbnail specimen, perfectly balanced in matrix - this is a superb example of this rare silver-species, where good quality is only known from a few finds at this location. This specimen would have been from the Larson/Swoboda diggings here in the 1970s. Photo by Mark Mauthner.
