Three-Stone Star Sapphire and Diamond Gold Ring

This is a three-stone cocktail or engagement-style ring featuring a center oval cabochon sapphire, likely a star sapphire given its translucency and blue-grey color. The center stone is held by four gold prongs and is flanked by two smaller round brilliant-cut accent stones, which appear to be diamonds or high-quality stimulants, set in gold shoulders. The band is a thin, polished yellow gold, likely 10k or 14k based on typical mid-20th-century construction. The center sapphire exhibits a dense, milky blue saturation characteristic of genuine star sapphires, though the 'star' (asterism) is not clearly visible in this lighting. The setting style suggests a mid-century modern aesthetic, possibly from the 1960s or 1970s. Regarding condition, the metal shows signs of light surface wear and minor scratching consistent with age. There is a slight patina on the underside of the setting. No obvious maker's marks are visible in the image, but such pieces often contain stamps inside the shank. The craftsmanship appears to be standard commercial fine jewelry quality, with symmetrical prong work and a tapered shank design.
