How to clean a copper/pearl necklace without damaging pearl?
I own a necklace which has the particular problem of being made with both copper and pearl. The design consists of a copper-casted imitation of a grooved scallop shell, with a small freshwater pearl inlaid, along with a rather intricate chain.
I am looking for a solution which would help me remove the oxidation from the copper thoroughly from all fine details, without damaging the pearl. All of the solutions that I've searched on the internet said to put it into some acidic substance like salad dressing or Worcestshire sauce, but acids damage pearls. Does anyone else have an alternative?
