The discoloration of white gold jewelry, often presenting as a yellowish tint, stems primarily from the alloy’s composition. White gold is not naturally white; it’s created by combining gold with white metals such as nickel, palladium, or silver. To achieve a bright, white appearance, it is usually plated with rhodium, a hard, silvery-white metal. Over time, this rhodium plating can wear away due to friction, exposure to chemicals, or general use, revealing the underlying alloy’s natural yellow hue.
Maintaining the desired appearance of white gold is important for both aesthetic and value retention purposes. The original luster and brightness contribute significantly to the jewelry’s visual appeal and perceived quality. Regular cleaning and periodic rhodium replating are commonly employed to restore the original color and protect the underlying alloy from wear and corrosion. These practices ensure the longevity and sustained attractiveness of white gold pieces.
