Victorian Niello and Rose Gold Twisted Link Longuard Chain
An antique Victorian longuard chain with alternating twisted niello and rose gold links, with a swivel. Circa 1890.
Niello is an ancient type of decorative inlay in which the design is engraved in the metal base, usually silver. The engraving is then filled in with an alloy of metallic sulfides that become black when heated. The effect is a velvety black and silver pattern. Niello was revived in the nineteenth century and was especially used in Russia and France.
