Gold-tone metal and pink cabochon butterfly brooch

The item presented is a decorative costume jewelry brooch crafted in the shape of a butterfly. The piece features a textured gold-tone metal base with openwork settings that secure four pear-shaped, smooth pink cabochon inserts, likely made of molded glass or plastic, simulating stones such as coral or rose quartz. The reverse side displays a standard pin stem and safety rolling catch mechanism attached across the upper wings, consistent with mid-20th-century construction methods for costume jewelry. There are no visible maker's marks, stamps, or signatures legible in the provided photograph. The metal surfaces exhibit a warm, brushed or textured finish with minor surface wear and a slight patina appropriate for older costume pieces. The overall aesthetic is consistent with mid-century novelty jewelry popular from the 1950s through the 1970s. The identification rests strictly on visual observation of the form and materials without the aid of any verifiable hallmarks.

Based on what I can see in the photograph, this decorative costume jewelry brooch features a textured gold-tone metal base and four pear-shaped pink cabochons shaped like a butterfly. The piece exhibits mid-20th-century construction characteristics, including a standard pin stem and safety rolling catch. However, I can't verify from a photo the exact composition of the metal, the precise material of the pink inserts, or the potential presence of faint, obscured maker's marks. I would need physical inspection to confirm these material details and any potential attribution. The estimated value range of $45–$85 assumes the piece dates to the mid-century novelty jewelry era and remains in typical vintage condition with minor surface wear and patina. General market demand for unbranded mid-century costume jewelry remains modest, appealing primarily to collectors of vintage accessories. To fully evaluate the piece, physical examination, hallmark verification, and expert appraisal would be necessary. If the item were determined to be a later reproduction, replica, or an unattributed piece created 'in the style of' mid-century novelty designs rather than a period piece, the market value would likely decrease to a range of $15–$30.
