AI Appraisal Estimate

This unique circular brooch is a prime example of steampunk-style assemblage jewelry, measuring approximately 2-2.5 inches in diameter. The piece is constructed on a perforated silver-toned metal base with an outer twisted wire border. It features a collage of mechanical horological components, most notably a larger silver-toned 'Gervais-Penard Electronic' watch face at the top, which retains its Arabic 12, 3, 6, and 9 numerals and baton indices but lacks hands. Accenting the face are various watch movements, including brass and steel gears, plates with visible rubies/jewels, and a smaller rectangular watch dial. Scattered throughout the composition are nine clear, faceted faux-diamond rhinestones that provide contrast against the industrial metal. The construction appears to be a mid-to-late 20th-century artisan creation using repurposed parts from the early-to-mid 1900s. The condition exhibits a heavy aged patina consistent with the 'upcycled' aesthetic, including surface oxidation on the movement gears and minor wear on the main dial's finish. The craftsmanship is eccentric, relying on adhesive or solder to secure the dense, layered arrangement of mechanical fragments onto the filigree-style base.

I have conducted a visual examination of this vintage circular steampunk assemblage brooch. This piece, measuring approximately 2.25 inches, is a characteristic 'found object' artisan creation likely dating from the 1970s to 1980s, utilizing watch components from the mid-20th century. The centerpiece, a Gervais-Penard Electronic dial, is a mid-tier Swiss-made component that adds brand recognition but lacks significant horological value in this non-functional state. The construction exhibits a heavy patina and visible oxidation which, while aesthetically consistent with the steampunk genre, indicates lower-grade base metals. The use of clear rhinestones suggests a bridge between industrial and decorative costume jewelry. Market demand for unsigned assemblage pieces remains steady among niche collectors but is capped by the lack of a known artist's signature or precious metal content. Comparable sales for similar diameter 'watch movement' brooches typically fall within the sub-$100 range. The value is primarily driven by its aesthetic appeal as a wearable piece of art rather than intrinsic material worth. Limitations of this appraisal include the inability to verify the security of the adhesives or solder points without physical manipulation. From images alone, I cannot determine if the 'rubies' in the movements are genuine synthetic corundum or mere glass. A definitive authentication would require a tactile inspection for structural integrity and a chemical test of the silver-toned base to rule out high-purity silver content, though it currently appears to be plate or nickel-silver.
