Just wondering if anyone knows a safe way to clean and polish cheap jewelry...? I have a set of earrings and bracelet that I really love....but the silver is turning absolutely black! I would like to polish/clean/shine up the silver--but the jewelry also contains fake gemstones. They are pink (not sure what they are supposed to be, if anything) and probably just made out of plastic. Can I clean the silver parts without damaging the "gemstones"...? Thanks!
