Gold tone magnifying glass pendant, bears the mark 'BOUCHER' (not authenticated)

This piece is a gold-tone metal accessory, featuring a circular magnifying glass lens encased in a ridged bezel, topped with the figural representation of a ballet dancer or performer in a dynamic pose. The metal displays a textured, brushed, or satin-like gold-tone finish with detailed etchings. Visible on the leg of the figural dancer is an impressed copyright symbol and the capitalized text reading '(C) BOUCHER'. Additionally, there are numbers stamped near the bottom rim of the circular magnifying frame, which appear to read '9545 N' or similar. The object has a small jump ring or loop attached near the dancer's upper body, suggesting it was designed to be worn as a pendant or charm rather than strictly as a brooch, though the owner's unverified notes suggest a dual or related function. The physical condition exhibits minor surface wear and patina consistent with age, but no major structural damage or missing parts are readily apparent from the photograph. The craftsmanship displays careful texturing on the metal components and a clean bezel setting for the glass lens. The user supplies context claiming this is a brooch, but this claim remains unverified by physical inspection. The attribution to Boucher is based purely on the observation of the stamped mark visible on the metal surface, which is unauthenticated and presented as a hypothesis.

Based on what I can see in the provided image, this item is a gold-tone metal accessory featuring a circular magnifying glass and a figural ballet dancer, bearing a mark that reads 'BOUCHER'. The owner identifies this piece as a brooch and attributes it to Marcel Boucher, though I cannot verify this claim from a photograph alone. Based on the assumption that the attribution is correct, similar vintage designer costume jewelry pieces typically command a market range of $150 to $300, depending on condition and collector demand. However, visible markings can be forged or misread, and I would need physical inspection to confirm the materials, age, and hallmark integrity. If physical inspection reveals the piece to be a later reproduction, replica, or an unattributed item in the style of Boucher, the value would likely decrease significantly, dropping into the $30-$75 range. The physical condition exhibits minor surface wear and patina consistent with age, but assessing structural integrity requires a hands-on evaluation. To establish a more precise valuation and resolve the attribution hypothesis, further steps would be needed, including in-person examination by a qualified costume jewelry expert, hallmark verification, and a search for matching catalog documentation. Without physical authentication, this estimate remains conditional upon the accuracy of the owner's supplied identification.
