Whether a piece of jewelry composed of white gold exhibits magnetic properties depends entirely on its constituent metals. Gold, in its pure form, is not magnetic. White gold is an alloy, meaning it is a mixture of gold and other metals. These other metals, often including nickel, palladium, or manganese, are added to give the gold its white color and enhance its durability.
The addition of nickel is the most common reason for a white gold item to be slightly magnetic. Nickel is a ferromagnetic material, and even a small percentage can impart a noticeable magnetic attraction. Palladium and manganese, while sometimes used in white gold alloys, typically do not contribute to magnetic properties to the same extent as nickel. Consequently, understanding the alloy composition is crucial in determining the potential for magnetism. The alloy also effects the value and uses.
