Gold-Toned Ring with Rectangular Gemstone

The item is a gold-toned ring featuring a prominent rectangular, dark-colored gemstone set in a raised bezel. The ring's band appears to be constructed from a metallic material with a polished, reflective gold-tone finish, suggesting either solid gold, gold-plated, or gold-filled metal. Unfortunately, the exact material cannot be confirmed from the provided image due to the limited clarity. The setting for the gemstone is robust, with visible prongs or a bezel securely holding the stone in place. The sides of the ring's band directly below the setting exhibit an openwork design, appearing to consist of multiple parallel strands or wires, adding a decorative element to the piece. The overall construction suggests a medium to high level of craftsmanship. The condition of the ring shows some visible wear on the gold-toned surfaces, possibly indicating minor scratches or dulling consistent with regular use, but no major damage like cracks or significant deformities are discernible. There are no visible maker’s marks, signatures, or stamps evident in the blurred image. The style of the ring, with its substantial rectangular stone and intricate band design, suggests it could date from the mid-20th century to a more contemporary period, possibly with a vintage flair. The dark gemstone, though unidentifiable (potential candidates include onyx, sapphire, or a dark-colored tourmaline), contributes significantly to the overall aesthetic, providing a striking contrast to the gold-toned metal.
