Our 1930s carved coral drop earrings are hallmarked 800 for silver content on their screw back findings indicating European origins. They are just so wonderful with 7mm natural carved coral roses and a 5/8'' x 1/8'' carved drop. With an overall length of 1/8'' they wear beautifully.
The coral is so beautiful with natural hues of deep salmon to cream. I would date them at least back to 1930. The european, possibly Italian findings have not been polished and exhibit a time enhanced patina.
