White gold engagement and wedding rings, another common choice, get their gleaming silver hue from the addition of alloy metals such as palladium, zinc, copper, tin, and manganese. White gold jewelry of the highest quality is typically 18 karats, and is a combination of pure yellow gold and palladium. At Brilliance, we cover each of our white gold parts with a Rhodium plating, a gleaming, near-white metal coating that resembles platinum in appearance. To help preserve its original luster, white gold can be re-dipped in Rhodium on a regular basis.
