Size 9 Vintage Modernist Ring With Tension Set Clear Faceted Stone

Vintage Modernist Mid-Century Modern ring 18 karat gold electroplated. With a tension set clear faceted stone that looks like crystal (I don't think it's a diamond). Stamped 18 K HGE. Size 9-9.25. Unisex, so will be listed in both men and women categories. Lots of wear to the gold plating on the back and some - on the front and sides, as pictured.
