Vintage Silver-Tone Lozenge Brooch with Rhinestone Accent

This item is a vintage costume jewelry brooch featuring a refined, elongated diamond or lozenge shape. The piece is constructed from a silver-tone base metal with a brushed or semi-matte finish that provides a soft, metallic sheen. The most prominent design feature is a triangular inset located toward the upper apex, which is paved with small, clear round-cut rhinestones. These stones appear to be glass or crystal, set in a traditional pavé style. The overall design exhibits the sleek, geometric aesthetics common in Mid-Century Modern or Art Deco revival jewelry, likely dating from the mid-20th century. The brooch body has a subtle convex curve, adding three-dimensional depth to the flat geometric silhouette. Regarding condition, the metal surface shows minor surface abrasions and fine scratches consistent with age and previous wear. There is a slight patina or darkening in the recessed areas surrounding the rhinestones, though all stones appear to be present and intact. The craftsmanship is typical of mid-market commercial costume jewelry, emphasizing clean lines and balanced proportions rather than ornate detail. No visible stamps or maker's marks are discernible from the front, suggesting any branding would be located on the reverse pin mechanism.
