Two-tone gemstone clip earrings

This pair of earrings, resting in a human palm for scale, features a compact, curved hoop design equipped with clip-on backs and added white comfort pads. The physical construction combines yellow and white-toned metals, presenting a two-tone aesthetic. Each earring is centrally set with an oval-cut dark gemstone, possibly sapphire or onyx, which is flanked by swirling or pavé-set accent stones resembling small clear diamonds in a bright rhodium-plated section. The overall composition suggests mid-to-late 20th-century fashion jewelry or semi-fine jewelry, though exact material composition cannot be definitively determined from the photograph alone. There are no maker's marks, stamps, or hallmarks directly readable in the visible image angles. The condition appears well-preserved with intact stones and functional hinges, showing minimal surface wear. The identification rests purely on visual observation of the physical characteristics, shape, and construction style without any implied attribution or brand association.

Based on what I can see in the photograph, this pair of two-tone clip earrings features a compact, curved hoop design combining yellow and white-toned metals. Each piece is centrally set with an oval-cut dark gemstone, possibly sapphire or onyx, flanked by small clear accent stones in a bright rhodium-plated section. The overall construction suggests mid-to-late 20th-century fashion or semi-fine jewelry. However, I can't verify from a photo whether the metals are precious or base, nor can I confirm the true identity of the gemstones without physical testing. There are no clearly readable maker's marks or hallmarks visible in the image angles. The condition appears well-preserved with intact stones and functional hinges, showing minimal surface wear. Assuming these are semi-fine materials consistent with vintage fashion jewelry, comparable items typically trade in the $150 to $350 range, driven by moderate demand for retro clip-on designs. If physical inspection reveals the materials to be mere base metals with simulated stones, the value would decrease significantly to the $30 to $75 range. To establish a more precise valuation and authenticate the piece, I would need physical inspection to examine metal purity stamps, gemstone refractive properties, and overall construction quality.
