Vintage Silver-Tone Dome Ring with Red Gemstones

This is a vintage cluster ring designed in a distinctive domed or 'bombé' style, commonly associated with mid-century fashion jewelry. The ring features a high-profile, circular setting constructed from a silver-toned metal, which appears to be either sterling silver with a natural aged patina or a plated base metal showing signs of oxidation. The central focal point is a larger round red gemstone, which is surrounded by multiple tiers of smaller, similarly colored stones. While the photo's focus prevents a definitive identification of the stones, their deep crimson hue is characteristic of bohemian garnets, synthetic rubies, or high-quality glass paste commonly used in costume jewelry from the 1940s through the 1960s. The stones are held in place by small individual prongs within a decorative, openwork filigree or basket-style setting that allows light to penetrate from beneath. Regarding condition, the metal exhibits significant darkening or tarnish, particularly in the recessed areas of the setting, though this patina is often desirable in vintage pieces as it highlights the intricate metalwork. The item is presented in a light blue jewelry box with a cream-colored velvet or flocking insert, which appears aged and shows some staining and wear. There are no maker's marks visible in the image, but the craftsmanship suggests a mass-produced yet well-constructed piece of decorative jewelry from the mid-20th century.
