Vintage Czech Gold Tone Blue & Gray Rhinestone Screw Back Earrings

Vintage Czech Gold Tone Blue & Gray Rhinestone Screw Back Earrings. Really pretty, but they do have some wear. One is missing 2 of the tiny gray stones. They also have a little tarnishing. I did clean them with baking soda and a soft toothbrush. They are approximately. 50" in diameter.
