AI Item Analysis

This decorative figural brooch takes the shape of a traditional folding fan, featuring intricate multi-colored enamel work and metallic detailing. The primary background fields display a vibrant translucent blue plique-à-jour or translucent enamel over textured metal, framing two distinct silver figures that appear to depict traditional Thai dancers or mythological characters in dynamic poses. The upper guard and framing elements are highlighted with cream-colored and yellow enamel, accented by small circular dots of deep blue and red enamel along the scalloped edge. The lower pivot point of the fan is decorated with a small blue and red enameled circular motif, leading into pierced lower ribs rendered in silver tone. The physical condition appears generally well-preserved with some expected minor surface wear and patina consistent with vintage jewelry, though the structural integrity and enamel retention look largely intact based on visual inspection. The piece does not clearly display the reverse side in the provided photo, but the owner reports it is marked 'Made in Siam Sterling', a text claim that remains unverified from this single perspective. The stylistic characteristics, choice of materials, and iconography are consistent with mid-20th-century export jewelry from Siam, which frequently utilized traditional motifs and silver-working techniques. The identification rests primarily on the distinct fan silhouette, the inclusion of Thai dancing figures, and the characteristic enamel palette, but the attribution is unauthenticated.

AI Appraisal Report

Based on what I can see in the provided photograph, this decorative figural brooch takes the shape of a folding fan with multi-colored enamel work and silver-toned metal, featuring traditional Thai dancing figures. Per user submission: the owner identifies this as marked 'Made in Siam Sterling.' I cannot verify from a photo whether the metal content is indeed sterling or if the hallmark is period-correct, and would need physical inspection to confirm. My appraisal estimate of $150-$250 assumes the owner's claim is correct regarding its mid-20th-century origin in Siam and silver composition. Vintage export jewelry featuring niello and enamel work from this region enjoys steady collector interest for its distinct iconography and craftsmanship, though values fluctuate based on condition and enamel retention. If physical inspection reveals the piece to be a later reproduction, modern replica, copy, or produced 'in the style of' without actual period silver or manufacture, the value would likely drop significantly to the $40-$75 range. To confirm attribution and potential value, one would need in-person examination, hallmark verification, and expert appraisal.
