Vintage 10k Gold Amethyst and White Sapphire Halo Ring

This is a vintage cluster-style halo ring crafted in 10-karat yellow gold. The piece features a prominent round-cut center stone, identified as an amethyst weighing approximately 2.5 carats, which exhibits a vibrant deep purple hue and checkerboard-style faceting on the crown. It is surrounded by a halo of twelve smaller, round-cut white gemstones, likely white sapphires or possibly zircons, set in a scalloped gallery. The ring is shown on a metal mandrel indicating a US size 10. The construction displays a mid-20th-century aesthetic with a relatively slender shank. Condition-wise, the piece shows moderate signs of age-appropriate wear; there is visible surface abrasion on the facet junctions of the amethyst and some accumulation of debris behind the settings. The side stones appear slightly dull, which may be due to dirt buildup or mild surface scuffing. No prominent maker's marks are visible in the provided image, but the metal composition is confirmed as 10k by the provided context. The craftsmanship is indicative of commercial fine jewelry production.
