These lovely earrings are trademarked Theda (Ideal Mfg.Co of Providence, RI since 1921). They are also hallmarked Sterling on the back of the earring and on the bottom of the screw. The screw back earrings are 5/8" in diameter and feature tiny Comet Argent Light rhinestones on the top. The sides are scalloped and the earrings are very dainty and emit a delicate sparkle.
They are in excellent vintage condition.
