An aesthetic, old-time St Andreasberg thumbnail of highly lustrous, metallic-gray Pyrargyrite. The main crystal has an attractive and sharp triangular form with mirror faces. This is an excellent and representative specimen for this great mining region. Acquired in 1981 from legendary dealer Dick Bideux in Tucson.
