Gold-toned Claddagh-style drop earring with green faceted stone

This item appears to be a single drop earring featuring a traditional Irish Claddagh motif. The design consists of two hands holding a faceted, heart-shaped stone in a deep emerald-green color, topped with a stylized crown. The metal has a polished yellow-gold finish, though without visible hallmarks or testing, it is impossible to determine if the material is solid gold, gold-filled, or gold-plated costume jewelry. The green stone is stylistically consistent with emerald, glass, or cubic zirconia, requiring gemological inspection for identification. The earring is suspended from a lever-back (European) closure, which appears to have a small decorative fan or shell-like motif at the hinge. Small markings are visible on the lever-back mechanism, but they are insufficiently clear to read or verify as specific hallmarks or maker's marks from this image alone. The item's construction and style are consistent with late 20th-century or early 21st-century jewelry production. Overall condition appears good with minor surface reflections, though physical inspection would be required to rule out wear to any plating or security issues with the stone setting. Identification is based on visual motifs as no clear maker attribution is legible.

Based on my visual examination of the provided image, I have analyzed this single Claddagh-style drop earring. The item features a traditional Irish motif—hands holding a crowned heart—set with a faceted green stone, likely glass or synthetic cubic zirconia given the saturation and luster visible. While the metal exhibits a bright yellow-gold finish, I cannot determine from a photo if the piece is solid gold, gold-filled, or gold-tone costume jewelry. The lever-back closure appears to bear small markings; however, these are not legible enough to serve as a hypothesis for a specific maker or metal purity. Consequently, my valuation range of $15-$45 assumes the piece is contemporary costume jewelry or gold-plated silver of modest production. This estimate is based on the general market demand for Celtic-themed accessories in the secondary retail market. If physical inspection and scientific testing were to reveal the metal is solid 14k gold and the stone is a natural emerald, the value would likely increase significantly, potentially reaching the $150-$300 range for a single earring. Conversely, if it is confirmed as base-metal costume jewelry with significant plating wear not visible in the photograph, the value would sit at the lower end of the current estimate. A physical examination by a gemologist to perform a refractive index test on the stone and a touchstone acid test on the metal would be required to establish a more precise valuation. Without such verification, the piece must be treated as a decorative fashion item of indeterminate composition.
