As a devoted fan of JL Blin of Paris "¦ I know one when I see it. Although this is not signed "¦ I am absolutely sure it is JL Blin. The structure and the design says it all. It has two rows of dark and light topaz sparkly crystals leading down to a gorgeous centerpiece of crystals and faux pearls. It has a slide-in clasp. It's 16-1/2" long. The centerpiece is 2" x 1-1/2" and it's in excellent condition.
