Vintage Red Foiled Screw Back Earrings

Vintage art deco to retro era brass red foiled (likely Czech) rhinestone screwback earrings. One red glass is darker than the other, which I believe was intentional when they were made.

Fair to good condition with signs of age and wear as there is evidence of silver plating that has worn off.

Measures approx. 0.50”
