Vintage Emerald Green Uranium Glass Round Rhinestones Open Back Brooch Gold Tone

4 Emerald green round stones with 6 clear rhinestone accents. Brooch is vintage and the 3 outer stones are uranium rhinestones. Uranium glass stopped being produced in the 1920’s. In 1958 uranium glass production resumed then stopped after 1970. I estimate the brooch circa 1960’s. The center stone interestingly enough is not uranium glass. Each of the 3 outer stones articulate slightly which appears to be part of the design. They are very secure . The overall brooch condition is excellent.
