Cleaning Amber and Sterling Silver

How do I clean all my amber jewelry that is set in sterling silver? I don’t want to damage the amber, but the silver is getting all yellow & dingy.

Thanks!

Removing the amber is an option?

I’m not familiar with amber but if I’m worried about my silver polish, I dilute it with water and let it soak overnight.

one of these methods should work http://www.wikihow.com/Clean-Your-Silver-Jewelry
I would try the toothpaste or salt + aluminium foil

DO NOT USE ANY METHOD THAT INVOLVES ALUMINIUM FOIL AND/OR SODA.

You will ruin the surface finish of the silver - it will come out bright and clean (i.e. tarnish free), but with a minutely pitted surface.
