Gold-tone filigree and black cabochon brooch

This is a decorative brooch shown resting in an open human palm, providing a sense of scale relative to the hand. The piece is constructed with a yellow gold-tone metal base, featuring intricate filigree work on the leaf elements and smooth polished curved stems. Five oval-shaped, smooth black cabochon stones, which may be glass, onyx, or resin, are prong-set in a clustered formation at the top, resembling berries or grapes. The metal exhibits a warm, reflective finish with textured wirework within the leaf outlines, typical of mid-20th-century costume jewelry design. There is no visible maker's mark, signature, or hallmark discernible from this photographic angle; identification is based entirely on the visual characteristics of the materials, construction methods, and design motifs. The piece appears to be in generally good vintage condition with minor surface wear consistent with age, though physical inspection would be required to verify metal content and stone composition. The stylistic elements are broadly consistent with retro or mid-century costume jewelry, but any specific era or manufacturer remains unverified.

Based on what I can see in the photograph, this vintage costume brooch features a yellow gold-tone metal base with intricate filigree leaf elements and five oval black cabochon stones prong-set in a clustered formation. I cannot verify the exact metal content, stone composition, or manufacturer from a photograph alone, as there is no visible maker's mark discernible from this angle. Physical inspection would be required to confirm whether the metal is plated and whether the stones are glass, resin, or onyx. Assuming the stylistic hypothesis that this piece is a mid-century costume jewelry item of decent quality, comparable pieces in generally good vintage condition typically trade within the $45 to $85 range in the current secondary market, driven by steady demand for retro accessories. However, if physical examination reveals that the piece is a modern reproduction, copy, or unbranded 'in the style of' piece with lesser materials, the value would likely drop to the $15 to $30 range. To establish a more precise evaluation or confirm any potential attribution, in-person examination by a qualified jewelry appraiser and potential hallmark verification would be necessary.
