Byzantine-Style Multi-Stone Cabochon Button Earrings

A pair of substantial, three-dimensional button earrings designed in a rich Byzantine or Renaissance-Revival style. Each earring features a domed, yellow-gold toned metal base with a matte, textured finish. They are heavily embellished with multiple bezel-set round cabochon stones in alternating colors, including deep ruby-red, sapphire-blue, and iridescent clear or white stones, likely glass or semi-precious gems like garnet and lapis lazuli. The settings are architectural and bold, with protruding bezels that add significant depth and a crown-like silhouette to the pieces. The metalwork exhibits a distinct granulated or sandblasted texture typical of high-end costume jewelry from the mid-to-late 20th century, possibly by a designer like Chanel, Miriam Haskell, or Robert Goossens. While no hallmark is visible from the frontal view, the heavy construction suggests a luxury designer origin. The condition shows minor surface wear consistent with age, with a light patina developing in the recessed areas around the stone settings. All stones appear intact, though the underlying metal may show slight brassing or oxidation upon closer inspection of the reverse. These pieces likely date from the late 1980s to early 1990s when bold, 'Byzantine' aesthetic costume jewelry was at its peak popularity.
