The finish on this unused old stock necklace is very good. The beads vary from 7.5mm to about 11mm. The strands measure 12 inch to 15.5 inch and are attached to the Silvertone metal ends with tied bead tips. The 3 inch extension has 6mm and 7.5mm simulated pearls, and allows the necklace to fit like a 15.5 to 16 inch choker. The J-hook catch is marked 'Japan'.
