Art Deco Style Mother-of-Pearl and Rhinestone Brooch

This item is an oval-shaped brooch, likely crafted from a base metal, displaying an Art Deco or early-to-mid 20th-century aesthetic. Its primary feature is a central, elongated, white mother-of-pearl or similar iridiscent shell inlay, which exhibits a subtle luster and perhaps some natural variations in its surface. The mother-of-pearl is set within a geometric frame of what appears to be an aged brass or bronze-toned metal, suggesting a vintage patina. The frame is adorned with a total of six small, clear, faceted stones, possibly paste, crystal, or rhinestones, which are arranged in pairs above and below the central mother-of-pearl segment. These stones are individually set in bezel or claw settings, reflecting light and adding sparkle to the piece. The overall construction shows a fine filigree or milgrain-like detail along the edges of the metal frame, indicating attention to craftsmanship. There are no obvious signs of significant damage like major cracks or missing components, although the metal shows some discoloration consistent with age and use. The stones appear intact, though their brilliance might be somewhat subdued due to surface wear or dust. No specific maker's marks or signatures are visible in the provided image. The design's clean lines and decorative elements are characteristic of periods emphasizing geometric forms and elegant simplicity. This piece likely functioned as a decorative accessory to be pinned onto clothing.
