This centerpiece is an article 1122, gold-foil rivoli. It is 14 mm. If you didn't know, you would think this is a real emerald; the color is so deep and true. When you are taking the time and trouble to make a genuine Swarovski necklace or bracelet, you might as well go all the way to perfection with a Swarovski clasp. The centerpiece is set in a handmade sterling silver box clasp. It measures 28 mm from ring to ring.
