White gold is a gold alloy created by mixing pure gold with white-colored metals, most commonly nickel, palladium, or zinc. The alloying process gives the metal its characteristic silver-white tone, making it visually similar to platinum at a lower price point. Because pure gold is naturally yellow, white gold on its own still carries a faint yellowish cast, which is why nearly all white gold jewelry is finished with a thin layer of rhodium plating to achieve the crisp, bright white color consumers associate with the metal.
White gold is most commonly found in 14-karat (58.3% pure gold) and 18-karat (75% pure gold) formulations. The specific alloy composition varies by manufacturer and region: nickel-based white gold is harder and more durable, while palladium-based white gold is hypoallergenic and preferred for customers with nickel sensitivities. Because white gold jewelry contains real gold, it carries genuine intrinsic value and is stamped with a karat hallmark (14K, 18K, or 750) just like yellow or rose gold pieces.
The rhodium plating on white gold does wear down over time, typically within one to three years depending on wear habits, skin chemistry, and the original plating thickness. As the plating thins, white gold jewelry may take on a slightly warm or yellowish tone, which is the underlying gold alloy showing through. This is completely normal and not a defect. QJR's jewelers re-plate white gold rings, pendants, and bracelets regularly, restoring the original bright white finish and applying a fresh protective rhodium coat to extend the life of the piece.
