Vintage 1940s 1950s Rhinestone Screw Back Earrings

Lovely rhinestone screw back earrings circa the 1940s or 1950s. All set in a silver tone setting. No designer markings.
Measures about .75" across at its widest and just about 2" long.

Excellent vintage condition. One of them has some green patina. You can see this in the fourth photo. Could perhaps be cleaned, I have not tried.

Please note: These are vintage, preworn and/or preloved items. I do my utmost best to list any issues, but signs of wear should be expected, and there are occasionally small things I won't deem worthy of note. Please feel free to send me a missive with any questions. I'm truly happy to help in any way possible and I'm always up for a chat.
