Hello Séverin,

Have a thorough look under magnification to verify that the color sits on top of the material (rather than being the base metal if any silver layer is about to wear off); I don't think the latter possibility is likely here.

If it sits on top, a gentle touch up with a silver cloth will quickly remove yellow oxidation of silver alloys while remnants of gilding tend to be more stubborn. (More abrasive silver cleaning products can remove both!)

Regards,
Kai
