Silver Filigree Opal Ladies Ring ?Hecho En Mexico? With Maker?s Mark Size 7. A ring that sells itself with the beauty of a single stone. Told by several people I trust that it is an Opal and then confirmed four times on a gem identification app under different lighting. The colors sell this ring far better than I could! Ring is marked ? HECHO EN MEXICO? with what appears to be a makers mark of some kind. However because it?s not marked 925 or Sterling, I am listing more as a fashion ring. I would describe the top of the ring part as a simple filigree although it?s not complete as it?s solid underneath. Probably a purchase on a border town or on a tour from a cruise ship but it was purchased at an estate sale. Check out all the photos and see for yourself. Will ship USPS first class with tracking to winning buyer
