Vintage Antique 10K Gold with Opal Gemstones Libra Birthstone Promise Ring 7

Gorgeous Antique Vintage 10 karat gold stamped ring with one large & two small Opals. Grandmother gave this to my mom as purity ring (grandmothers birthstone as a Libra) that she used as a promise ring. This is circa 1960s with the old jeweler's stamp number they used to put on gold to identify. The opals are very iridescent in person & stunning! Lightweight but sturdy. EUC. Ring size 7, non-adjustable. Beautiful ring to pass on or use as a promise or engagement ring. *It looks like there's a chip/dent. There is not, it's how the stone & setting were fused. **** As this is an antique ring, the price is close to what I want to get for it. Please be considerate when making an offer.
