WHY DOES WHITE GOLD SOMETIMES APPEAR YELLOWISH?
Gold is yellow. There is no such thing as naturally occurring white gold. Historically, yellow gold is mixed (alloyed) with other metals to produce a white tone. Gold needs to be alloyed if used in jewelry because pure gold (24k) is too soft to be made into durable jewelry. Alloys used with gold to alter color and durability are copper, nickel, zinc, silver, and sometimes palladium. Nickel, which has been used to alloy the white color in gold, is now used less often due to potential allergic skin reactions. Gold alloyed in the European community is regulated to be Nickel Reduced or Nickel free. As such, some white gold now produced may have a slightly butter yellow tone as a result. To brighten nickel reduced white gold, jewelry is often rhodium plated to show a brighter (harder) silver finish and/or white gold may be alloyed with palladium to enhance the bright silver finish.
