Very cool and unique vintage Sterling silver and Black Onyx dangle drop clip on earrings from Mexico. These have nice pieces of Black Onyx in a nice thick sterling silver setting. The clips aren’t Sterling but they close securely. Markings:Mexico 925,I have acid tested this and it is Sterling Silver Condition: Good Condition there maybe some patina, Polishing will be up to the buyer Measurements: 1.75in x .5in 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. You pick your patina! I don’t polish as some people prefer the patina. 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!
