Mid Century earrings, fine gold filled with rose design and a hanging leaf, with a center stone , black with very little faceting , when these were given to my mother they gifter called them black diamonds, but this is anecdotal, they might be a form of hematite, although they seem too black for that. They are marked for the gold filled on the screw back . Very fine quality, these came originally from a fine jewelry store. In very good condition, each one is 1" long total length.
