16.75", 38 grams, patterns on both sides of curb, High-quality heavy gold fill curb chain measures just under 1/4" wide. This material is a long-wearing 19th century alternative to solid gold; it's made by mechanically bonding a thick layer of real gold to a metal core. It's nicer and more durable than any gold plate made now. Some tarnish on XL bolt ring, dog clip. Excellent quality, originally was a watch chain. Probably American c. 1910.
