White Gold Rhodium Bonded Floral Pendant with White Cats Eye Petal-Shaped Stones and CZ Center in Silvertone. Nouveau Centerpiece is a brilliant combination of heart shapes and CZ to form a beautiful floral design. White Gold Rhodium Bond is achieved using an electroplating process that coats the item with heavy layers of rhodium, a close cousin of platinum that costs three times as much, which gives our jewelry a platinum luster.
