Do not use any kind of polish!
All polishes contain abrasive and will remove the thin layer of gold. You could try asking Cartier if they recommend anything. I think it's better to have the discolored gold than to have the silver show through which will turn black. Best, Martin
Gold layer is gone there

The dark is silver reaction with your skin/transpiration. Most probably silversulfide. Gold is inert. So either you polish it with silver cloth, leave it as it is or have gold layer replaced. You could even try putting a gold leaf to try it yourself.
