Gold-tone pendant featuring a George V coin-style mount

This jewelry piece consists of a yellow-metal pendant suspended from a gold-tone Byzantine-style link chain. The focal point of the pendant is a disc bearing an effigy consistent with the portrait of King George V, facing left. The surrounding circumscription, though partially obscured by the mounting, includes legible text consistent with 'GEORGIVS V D. G. BRITT: OMN: REX F. D. IND: IMP:'. The central disc is housed within an ornate, multi-tiered bezel. The inner rim features a twisted rope design, followed by a halo of small, clear stones (consistent in appearance with diamonds or synthetic substitutes), and a decorative scalloped or fluted base at the bottom. The bail is uniquely shaped with a pointed, foliate-like design and is set with two additional clear stones. Based on the visible portrait, the central element appears to be styled after a British Gold Sovereign or Half-Sovereign coin issued between 1911 and 1936; however, without a view of the reverse for a date or physical testing of the metal, this remains a stylistic hypothesis. The piece shows signs of minor surface wear and oxidation consistent with age. No hallmarks or maker's marks are visible in the image to verify the metal purity or designer.

Based on the visual evidence, I have examined this yellow-metal pendant featuring a central disc styled after a King George V British sovereign. In my assessment, the value of the piece depends heavily on the metal purity and the nature of the stones, which I cannot verify from a photo alone. The pendant bears text consistent with a George V sovereign; however, this should be treated as a working hypothesis as coin-style jewelry is frequently produced using base-metal tokens or lower-karat reproductions rather than numismatic-grade gold coins. The stones in the halo and bail appear consistent with cubic zirconia or glass, though I cannot rule out the possibility of small diamonds without a thermal conductivity test. Based on what I can see, the Byzantine-style chain and the ornate mount exhibit surface wear suggesting a gold-plated or low-karat gold construction. I am estimating the value within the $400 - $600 range, assuming a 10k to 14k gold-filled or low-karat composition with a possible bullion-adjacent disc. To move beyond this hypothesis, a physical inspection is required to perform an acid test for gold content and a loupe examination for hidden hallmarks. In the current market, there is steady demand for 'sovereign-style' jewelry; however, if physical testing reveals the piece to be a base-metal replica or 'costume' item, the value would likely decrease to under $50. Conversely, if the coin and mount were verified as 22k and 18k gold respectively, the value would increase significantly based on the spot price of gold. Professional bullion testing and stone verification are necessary for a higher degree of certainty.
