White gold was first used in jewelry in the 1920s, closely following the popularity - and rarity - of the similarly colored platinum. Since the 1920’s white gold has been fashionable in jewelry as a more affordable alternative to platinum. This trend is particularly evident in art deco jewelry. White gold is currently the most popular precious metal within the U.S. During World War II, the use of platinum and nickel were prohibited outside the military. Palladium white gold alloys then became standard, and after the war, the cheaper alloys containing nickel prevailed.

As gold is normally yellow, the white sheen is achieved by alloying the gold with another metal such as nickel, palladium, platinum or silver; and then plating the ring with rhodium. The more gold that is contained in the alloy, the more yellow the ’white’ gold will appear in color, meaning that 18K white gold is naturally more yellow than 10K. This is why white gold rings are traditionally plated with rhodium - to get the whitest possible finish. Rhodium also helps protects the ring from wear and tear - if silver is used in an alloy, it could become tarnished by the air, and rhodium is more resistant.

Like anything, white gold will develop small scratches. These will be most noticeable at first, but will fade over time to a more pleasing patina. If the ring picks up any surface dirt, you can rinse this off under cold water and dry the ring carefully with a soft cloth. The shine of the ring may dull from contact with detergents, moisturizer and soaps so even a quick buff with a soft cloth will improve the appearance of the ring. The rhodium plating will wear off over time, but this should happen gradually and fairly evenly. The item can always be re-plated.
