Gold gemstone ring with square bezel

This piece features a yellow gold-toned metal band supporting a prominent square-shaped bezel setting. The face of the ring contains a dark reddish-brown to black gemstone, possibly garnet or a similar dark stone, featuring a faceted or stepped table design. At the very center of this dark stone is a small, square illusion-type setting holding a tiny clear accent stone, which visually resembles a diamond chip. The metal exhibits minor surface wear and patina consistent with age and prior use. There are no clearly legible maker's marks, stamps, or hallmarks visible from this angle. The owner supplies the unverified note that the item is a '10k garnet' ring, but this metal purity and specific gemstone identity cannot be verified from a photograph alone. Stylistically, the geometric stepped bezel and central illusion setting suggest an mid-20th-century design, such as a Retro or Art Deco revival period piece, though the exact age and materials remain unauthenticated.

Based on what I can see in the photograph, this piece features a yellow gold-toned band with a square bezel setting housing a dark reddish-brown to black gemstone and a central illusion-set accent stone. Per user submission: the item is a '10k garnet' ring. I cannot verify the metal purity, gemstone identity, or age from a photo alone; physical inspection, gemological testing, and hallmark verification would be needed to confirm these attributes. Assuming the owner's claim of 10k gold and garnet is correct, items of this mid-20th-century aesthetic typically trade within the $150 to $250 range in the current secondary market, driven by moderate demand for vintage geometric and Retro-style jewelry. If physical testing reveals the piece is a modern reproduction, gold-plated base metal, or a synthetic imitation rather than genuine garnet and 10k gold, the market value would drop significantly, likely to the $30 to $60 range. This estimate assumes the owner's attribution is correct, but the final valuation strictly depends on professional physical authentication.
