Three-stone halo sapphire and diamond ring

This is a three-stone 'trilogy' style ring featuring three oval-cut blue sapphires, each surrounded by a pavé-set halo of small brilliant-cut white diamonds or diamond simulants. The stones are set in a white metal mount, likely platinum, white gold, or sterling silver, and are mounted on a simple band. The central sapphire appears slightly larger than the two flanking stones, creating a graduated aesthetic. The sapphires exhibit a deep, royal blue saturation with visible facet edges, suggesting they are either natural or high-quality synthetic stones. The halo settings use multiple small prongs to secure the accent stones. In terms of condition, the ring appears to be in good estate condition, though light surface scratches on the metal band and slight dullness in the accent stones suggest light previous wear. The design is contemporary, likely dating from the late 20th century to the early 21st century, emulating classic Victorian and Edwardian cluster styles. The craftsmanship appears solid with well-aligned prongs and symmetrical settings, though without a hallmark, the exact metal purity remains unverified.
