Very Pretty Sterling Silver Tourmaline and Simulated Opal Ring. This has a beautiful center Tourmaline Stone with opal details on the side of the band. The stone looks more purplish then the pictures show. I have tested the stone with a Presidium Gem Tester Markings: 925 R CN ,I have acid tested this and it is Sterling Silver Condition: Good Condition, there is some patina, polishing will be up to the buyer Measurements: Size 8.25 Thank you for looking! Please don't hesitate to ask if you have any questions. I do my best to clean and look over every piece and list any flaws that I see but I may have missed something. Vintage or used jewelry might have tarnishing, small scratches in the finish and wear. I try to be as honest as I can about the condition. I am no expert but will share all the info I know and find during research. Please see all pics as they are a big part of my description. Thanks again for stopping by my shop and looking at my treasures!
