Vintage Style Sterling Silver Burmese Ruby Ring Size 6

This beautiful ring features a stunning Burmese Ruby at the center. Oval cut, it has fancy decorative work around it, filled with clear stones. They tested as diamonds, but may be zircons. The ring is stamped "Y" inside a circle and also "925 CHINA". I have not been able to identify this maker. Made of sterling silver, it may also be plated with rhodium to keep it looking it's best. The stunning Ruby measures about 5mm by 8mm in size. The ring is a size 6, and is in nearly perfect condition. From a high end estate.
