Many refineries and manufacturers are now offering a white gold are nickel, and the other is an alloy of gold, white is white enough not to need rhodium plating by mixing the Palladium. The golden yellow. White similar to platinum. However, the high production costs. It is not as popular. The manufacturer, but that we have used this method of production. To increase the lifetime of wearing white and gold.
