Vintage 1980s Art Deco Revival Fan Brooch

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.
