Vintage Opal and 14k Gold Earrings from the 1960s. Stamped 14k solid gold and 4 natural opals. Large opal is approx 4mm diameter, small opal is approx 2mm diameter. Total length of the earring is approx 1.4 inches. Butterfly back closure. Inherited from my grandmother, I have never worn them, but in trying them on for photos found them lightweight and comfortable while still making a big impact. Very pretty and delicate!
