Vintage Gold & Navy Statement Earrings with Rope Gold Detailing

Pretty Vintage Earrings with Gold Rope Like Detailing Around Edge and Large Navy/Black Stone in Middle. To me the stone looks dark navy in the sunlight but looks black in inside lighting. No damage! Super cute and classy earrings. No markings so assuming its just costume jewelry from the 80s-90s. Very light weight. Missing backs. Measurements: 0.5in Width 0.75in Length
