This necklace has graduated navy blue beads on a heavy, highly textured double-link chain. Between each bead is a flat goldtone metal spacer. The necklace is 35" long, plus there is a 3" extension. A hang tag next to the lobster clasp is marked "CN" and this tag has a rather elaborate etched design on the other side, which possibly has the letters "TS" in the design, although I'm not sure! I haven't been able to track down any information on this designer, though I have seen a listing that claims it is a Paris, France designer. The necklace is in excellent condition.
