Fabulous stunning antique 19th century gunmetal or so-called Berlin iron long collet set crystal sautoir necklace. Mid to late 19th century, probably French. These necklaces were also originally used as muff chains, hanging the fur muff around the wearer's neck, where it would fall at about waist length. The watch style clasp and ring could also be used to hang items such as a lorgnette or a lady's watch. This piece is long enough to wear three times around the neck or wear as a longer sautoir. It has exactly 100 stations with colorless stones in bezel or collet settings. The stones and settings are just under 5 millimeters in diameter. The stones are either glass paste or rock crystal. So-called Berlin iron jewelry originated in the late 18th century in Germany. It was made from iron or base metal and lacquered dark gunmetal/black to prevent rusting. By the early 1800's it was also being manufactured in France and England and primarily used as mourning jewelry. Its popularity in Europe continued throughout the 19th century. 59 1/4 inches long. Excellent condition. The stones are brilliant and much brighter than the photos show. A few of the stones have microscopic flea bite losses which are not visible without a loupe. Display form is life size. Photos enlarged to show detail.
