For sale is this great, Art Deco era, 18k White Gold Filigree Diamond Watch Chain. It measures almost 14" long and has 1.5mm wide filigree links. There are five, bezel set diamond links weighing approximately 0.10 points each for a total carat weight of 1/2 carat. The tested, 18k white gold chain weighs 6 grams and has one small bend in one link (see close up picture). The diamonds are clean and sparking (VS-1, G) and the piece can be worn doubled around the wrist as a bracelet, if desired. It reminds me of the "Diamonds by the Yard" style sold by Tiffany's.
