Vintage Moonstone Big Flower Post Earrings

Moonstone big flower sparkly domed post earrings with moonstones, possible opal and smaller clear stones all set in a rose gold metal setting. Possibly vintage. Approx 3/4” across. Moonstone & opal appear to be real, but I am not a gemologist or a jeweler. I would assume clear stones are cz. Earrings appear to be in great condition. The stones sparkle beautifully. The setting is tarnished in spots, but that’s really only visible on the back of the earring.
