An exceptional, high-quality classic specimen from the historic Sala Silver Mine in Sweden, which ceased primary operations in 1908. This piece perfectly illustrates the classic paragenesis of the famous Bergslagen mining district.
The specimen features  matrix of white dolomite micro silver dendrites  concentrations of dark,   acanthite (Ag₂S), the premier silver sulfide. The stark, monochromatic contrast between the dark silver minerals and the bright dolomite matrix gives this piece outstanding eye appeal and superb shelf presence. At 84 grams, this is a one off  rare specimen from legendary European locality.
