White Gold turning Yellow???
Why is my White Gold Ring turning yellow?
A familiar question around here!
Pure gold is yellow in colour. White gold if 9K is 37.5% pure gold & if 18K is 75% pure gold, but to appear white is alloyed with Palladium and Silver. Then to appear bright, shiny & white, White gold Jewellery often has a Rhodium plate over the top. Rhodium plating needs to be reapplied every 2 years or so.
Once the Rhodium wears off, the white gold is exposed to the atmosphere & can oxidise, sometimes giving a yellowish tinge.
A visit to your local Jeweller, for a polish and reapplication of Rhodium will have your rings looking like new.
Perhaps better than you remember!
