Gold-tone brooch with green cabochon

This is a circular brooch featuring a polished dark green cabochon stone paired with a textured filigree leaf motif. The item is constructed from a yellow gold-toned metal, displaying a combination of smooth polished surfaces and intricate wirework detailing typical of mid-20th-century costume jewelry design. The brooch measures approximately one to two inches in diameter and has a pin stem closure stretching across the open circular frame, though the hinge and clasp mechanisms are partially obscured in this angle. There are no maker's marks, hallmarks, or signatures clearly legible in the image, so the identification is based entirely on visual observation of the piece's construction, materials, and stylistic elements. The overall aesthetic suggests a vintage fashion accessory possibly dating from the mid-century period, though exact age, metal purity, and gemstone identity remain unverified without physical inspection and testing.

Based on what I can see in the photograph, this circular brooch features a dark green cabochon stone paired with a textured, gold-toned filigree leaf motif, pointing stylistically toward a mid-20th-century costume jewelry aesthetic. I can't verify from a photo alone the metal purity, the exact composition of the stone, or the presence of any maker's marks, as the hinge and clasp mechanisms and reverse side are partially obscured and unmarked identifiers are not legible. An in-person physical inspection would be required to evaluate the quality of the plating and construction more closely. My value estimate of $45 to $85 is based on the assumption that this piece is a vintage fashion accessory from the mid-century era in typical well-preserved vintage condition. General market demand for unbranded mid-century costume jewelry remains modest, with buyers generally seeking affordable vintage aesthetic accents rather than high-end investment pieces. To fully assess or support this attribution, an expert appraisal involving physical handling, hallmark verification, and material testing would be necessary. If this item were to turn out to be a modern reproduction, copy, or produced simply 'in the style of' vintage costume jewelry rather than a period piece, the market value would likely decrease significantly, falling closer to the $15 to $30 range.
