Gorgeous striped niello oblong twist fancy link chain – every other link retains traces of rose gold plate – original niello striped swivel pocket watch clasp – large spring clasp is of the same period – but not niello (black and silver striped) – would make a unique statement necklace – measures 16 1/2″ long x 3/16″ wide – marked only 800 – weighs a nice 12.9 grams. I will do my best to describe each item as accurately as possible and to the best of my knowledge. That being said, please note that my items are vintage, often unique and unless otherwise noted not in new/mint condition. Light wear consistent with age and use must be expected.
