Vintage 14K Yellow Gold Ring with Imitation Purple Star Sapphire and Diamond Accents

This is a vintage three-stone ring crafted from 14K yellow gold, featuring a central oval-shaped, imitation purple star sapphire cabochon flanked by two round, brilliant-cut diamonds. The central stone exhibits a distinct purple hue with a visible asterism, characteristic of a star sapphire, although noted as imitation. It is set securely in a bezel setting, providing a smooth, protective rim around its circumference. The two side diamonds are approximately 1/2 carat each, based on the provided context, and appear to be set in white gold or platinum bezels or partial bezels within the yellow gold band, creating a subtle mixed-metal aesthetic. The gold band itself appears solid and substantial, tapering slightly towards the shoulders on either side of the gemstones. The ring displays signs of wear consistent with its vintage nature, including minor surface scratches and possibly some patina on the gold, which are not explicitly visible in high detail but are expected for older jewelry. The craftsmanship suggests a commercially produced piece from the mid-20th century, possibly from the Retro or Mid-Century Modern period, given the robust setting and three-stone design. The overall structure is robust, indicating decent quality construction, though the use of an imitation star sapphire is a key identifier for its material value.
