The color combination in this necklace is mesmerizing. Silvery satin beads are laced with the palest clear green beads - a cool, crisp combination. The fish hook is marked Japan and I believe the beads are a combination of glass (the green beads and the round silver) and plastic or composite (the free-form silver beads). The shortest strand, including the ornate end pieces measures 14" and there is a 2.5" extension. Marvelous vintage condition!
