Art Nouveau Sterling Silver Earrings & Repousse/Crystals Screw-back Two Pair

Both sets are dainty in size, repousse just shy of 1 long x 1/2 wide. The ones with the crystals are approx 3/4 long x approx 3/4 wide. Both sets are very pretty and demure so they'd pretty much go with anything you wear. The repousse set remind me of leaves gently curling about a bud, perhaps for the night. The crystal set remind me of flowers with three teardrop cut prong set crystals (the flowers) and one marquise cut prong set crystal (the leaf) for each earring. Both sets are marked sterling (see photos). I believe both sets hail from the 1940's or 1950's. I have cleaned both sets w/a gentle brushing & have wiped the screw-on parts with alcohol, since they are quite old and have most likely been worn multiple times. I, personally, haven't worn them because I have pierced ears and have merely admired them over the many years I've owned them. The screw backs work great and the earrings themselves are in very good to excellent vintage/antique condition.
