This is a very unusual antique silver specimen with a coating of acanthite on the silver wires, it seems. It is a display-quality small cabinet piece, from the famous Himmelsfurst Mine in Germany. Many of the attractive, curving wires are over 3 cm in length, and their sinuous form as they twist and turn above the matrix is quite aesthetic. Little calcites add accent. A desirable display piece, complete all around, AND an important old classic! Obtained in trade from Ed David in the 1990s, and then long in the Obodda collection.
