Traditional pearl shortener clasp. Take a long string of beads, fastened, double it up, loop this through as a clasp. If really long, you can double again. An elegant solution to an old problem. Wear that too-long necklace as a shorter necklace. Antiquier than they look in the picture. Lead-free, nickel-free.
Lead-free. Nickel-free. 27mm x 22mm By the each.
