P and F Signed Amethyst Star Screw Earrings Vintage Jewelry
These earrings are star or flower shaped, with prong-set amethyst rhinestones in the centers. They are screw-on style, and the screw mechanism is marked "P & F" (the mechanisms work well). I haven't been able to track down who this designer is, but the earrings seem fairly old. (I polished them with a polishing cloth after I took the pictures, and they cleaned up nicely.) They certainly are beautiful earrings.
They will be shipped in a gift box.
