AI Appraisal Estimate

This item is a distinctive piece of costume jewelry, specifically a brooch or lapel pin, designed in an Art Deco Revival style likely dating from the mid-to-late 1980s. The piece is constructed from what appears to be a matte black finished metal, possibly aluminum or a coated base metal, featuring a series of concentric, tiered ridges that form a stylized fan or wing-like silhouette. At the base of the fan is a circular cabochon element in a vibrant, opaque cerulean or teal blue, which may be made of resin, plastic, or glass. The outer edge of the fan is notched or scalloped, adding a dynamic, geometric interest to the profile. The matte black finish provides a stark, modern contrast to the smooth, saturated blue center. Regarding condition, visible wear is present in the form of finish loss and chipping along the scalloped edges, revealing a lighter metallic substrate underneath. This indicates significant previous use and handling. The pin back is partially visible, appearing to be a standard safety catch or straight pin assembly. While no maker's marks are visible in the provided angle, the design language is characteristic of '80s era 'New Wave' or 'Post-Modern' fashion accessories that sought to reinterpret 1920s Deco aesthetics with industrial materials and bold color blocking. The craftsmanship highlights deliberate symmetry and clean lines, though the current state of the finish impacts its overall presentation and collectibility.

I have examined the digital images of this Art Deco Revival fan brooch. Stylistically, the piece aligns with the bold, geometric 'Post-Modern' aesthetic of the 1980s, utilizing matte-finished base metals and synthetic cabochons typical of the era's mass-market costume jewelry. While the design is striking, the condition is a significant factor in this valuation. My inspection reveals notable finish loss and silver-toned metal showing through the matte black coating at the ridges, which diminishes its 'deadstock' appeal for high-end vintage collectors. The blue cabochon appears to be a poured resin, which remains in good condition. Market demand for unsigned 1980s costume jewelry is currently steady but price-sensitive; comparables for non-designer pieces of this materials grade typically sell within the $20 to $50 range at boutique vintage outlets. The lack of a visible maker's mark (such as Ajane or Monet) further categorizes this as a 'fashion' rather than 'investment' piece. Authenticity as a period 1980s item is confirmed by the specific notched silhouette and the 'safety-pin' style hinge visible. However, full authentication is limited by the digital nature of this review. An in-person inspection would be required to verify the weight (confirming if it is aluminum or a heavier pot metal) and to check for hidden signatures under magnification. For a definitive insurance-grade appraisal, I would need to test the cabochon for material density and check the mechanical integrity of the pin-back assembly to ensure it remains wearable.
