Sterling silver glowy, iridescent moonstone post earrings ~1" dangle

Vintage sterling silver iridescent moonstone post earrings. Small moonstone ~.25" diameter on post, slightly larger moonstone dangle: ~1" total. Sterling silver is stamped on back (see pics) & moonstones are super glowy - see pics for how they catch the light, reflect, and glow. Gently worn, excellent condition, still quite beautiful.
