These drop earrings have lever backs in sterling with rose gold vermeil and Bohemian garnets. The back has the openings the let the light in. The earrings are 1 1/8" from the curve of the lever back for pierced ears. Marked 925 plus a smudge that I would guess is 9K or 10K for the lever backs. Probably 1940-1950. Excellent vintage condition.
