Oval Sapphire and Diamond Halo Cluster Ring

This is a vintage-style cluster ring featuring a center oval-cut blue sapphire, estimated at approximately 1.5 to 2.0 carats. The sapphire exhibits a deep, saturated navy blue color and is secured by four prongs within a white metal setting, likely 14k or 18k white gold or platinum. Surrounding the center stone is a multi-tiered halo of small, round-cut colorless diamonds, possibly single-cut or brilliant-cut, creating an impressive 'ball' or 'navette' shape profile. The diamonds appear to be pavé or grain-set, extending slightly down the shoulders of the band. The construction suggests a mid-20th-century design influence, common in the 1960s or 1970s. Regarding condition, the stones show visible surface grime and skin oil, which dulled the natural brilliance, common with daily wear. However, no major chips or fractures are immediately visible on the sapphire’s facet edges. The setting appears structurally sound with no missing accent stones. The craftsmanship shows high-quality pavé work, though a definitive maker's mark would require inspection of the interior shank. This style is often classified as a 'Princess Diana' or 'Royal' style halo, characterized by a bold center colored gemstone contrasted against a sparkling diamond surround.
