Gold-tone butterfly figural brooch with multicolored rhinestones

This is a vintage-style figural brooch taking the shape of an open-work butterfly, crafted from a yellow gold-toned base metal. The wings feature a delicate, webbed or filigree wirework lattice structure densely embellished with small, round, prong-set or paste-set rhinestones. The majority of the stones are clear or crystal-colored, interspersed with small accent rhinestones in vibrant primary and jewel tones including ruby red, sapphire blue, and emerald green scattered throughout the wing framework. The central body and antennae are textured to mimic the natural anatomy of a butterfly. The piece exhibits an even golden finish across the back and front metal framework, with no maker's marks or signatures visibly discernible from the provided photograph. The overall craftsmanship and design motifs are consistent with mid-to-late 20th-century costume jewelry production, often associated with the retro or vintage costume jewelry market. The condition appears well-preserved with intact stones and minimal surface wear visible in the image, though evaluation of wear and materials remains unverified without physical inspection.

Based on what I can see in the photograph, this vintage-style figural brooch features a yellow gold-toned open-work butterfly design embellished with clear and multicolored rhinestones. I can't verify from a photo the exact metal composition, stone types, or presence of maker's marks, and would need physical inspection to confirm whether the materials are base metal with paste stones or higher-end vintage costume components. The current appraisal value range of $75 to $150 reflects the typical market behavior for mid-to-late 20th-century costume jewelry of this type, assuming the attribution to vintage figural costume pieces is correct and that all stones are present and intact. Demand for whimsical retro figural brooches remains steady among collectors of vintage costume jewelry, though values largely depend on brand recognition and overall condition. If this piece were to turn out to be a modern reproduction, replica, copy, or produced simply in the style of mid-century costume jewelry without vintage provenance, the value would likely decrease significantly to the $25-$50 range. To confirm authenticity and exact age, an in-person examination, hallmark verification, and expert appraisal would be necessary to inspect the construction, clasp mechanisms, and stone setting techniques up close.
