For a temporary solution, you can try the following to help disguise the affected area: Note: Keep in mind that a camouflaged/modified piece of vintage or costume jewelry may lose monetary value.
Brush on a layer of DesignaSize gold leaf adhesive, apply a piece of silver leaf sheet then seal the leaf with DesignaSeal clear gloss top coat for protection of the leaf surface and resistance to tarnish. Obtain a thicker metal texture by applying two or more layers of metal leaf.
Another affordable solution is to use Krylon brand leafing pens to temporarily camouflage the damaged area. They are available in five metallic shades including silver, and are advertised to adhere to wood, metal, plastic, glass and more. Either option will leave you with metallic color-match issues to deal with and you may have to cover more than just the damaged area for color blending.
In the future, to help prolong the life of silver finished jewelry, following manufacturer's instructions, apply one or two coats of DesignaSeal then reapply as needed.
