Silver, Acanthite from Kongsberg Silver Mining District, Kongsberg, Buskerud, Norway [db_pics/mdpics/MD-164090a.jpg]

11.0 x 5.8 x 1.8 cm. A superb, incredibly aesthetic example from this most treasured of old European classic Silver locales. This piece has a beautiful dark patina caused by a micro layer of acanthite coating, and an exquisite complexity to the rope as it twists and turns like a living thing. The piece is VERY sturdy despite its elegant look, and this is a solid piece that is not flexible or "bendy" like some German silvers of this size. Ex. Dr. Eugene Meieran, Evan Jones Collections.

Silver, Acanthite, Chlorargyrite (Var: Bromian Chlorargyrite) from Comstock Lode, Comstock District, Storey Co., Nevada, USA [db_pics/mdpics/MD-166918b.jpg]

3.5 x 2.7 x 2.1 cm. Mineral specimens from the famous Comstock Lode at Virginia City, Nevada are RARE today, even in museums. The remoteness of the locality and lack of "showy" specimens precluded high-graders, other than for rich ore. The bonanza silver ores were depleted by 1878. This OLD-TIME, VERY RICH silver ore consists of bright, wire to hackly silver crystals in a matrix that is nearly SOLID bromian chlorargyrite! A free-standing, 4 mm, gemmy, yellow-green chlorargyrite crystal jumps out on the back of the piece. There are even dark blebs of acanthite scattered about. According to the label, this CLASSIC and RARE specimen was mined in 1885 (according to a more modern label with it) and comes from the Carl Stentz Collection of Laguna Hills, California.
