• This is the natural result when white gold tarnishes.  It's easier to see on white gold, but more difficult to see it on yellow gold.  On yellow gold, it makes your gold look dull and darker. Use our Tarnish Remover & Polishing Cream  to  remove tarnish.  Simply wipe some of the cream on to the metal, and use a soft cloth to buff the metal.  You will see black material coming off on the cloth - this is your tarnish!  After polishing, simply rinse in warm water and dry  with a soft cloth.
