I have a beautiful amethyst and diamond ring I wear daily. The amethyst is an emerald cut set in a bezel setting. There is a lot of dirt stuck around the edges, under the stone. I tried soaking it and scrubbing it - I even tried letting it sit in jewelry cleaner. The stone is super pretty and sparkly, but in certain lighting I can see the outline of debris around my stone. Any suggestions? Should I take it to my jeweler to get cleaned?
