Modernist White Metal Ring with Oval Blue Topaz and Baguette Accents

This is a modernist-style cocktail ring features a prominent oval-cut center gemstone of a light 'sky blue' hue, likely a blue topaz or an aquamarine, estimated to be approximately 2.5 to 3 carats in weight. The center stone is held in a unique semi-bezel tension style setting. Flanking the center stone on the shoulders are two clear rectangular-cut stones, likely baguette diamonds or white topazes, set within thick rectangular channels. The band is a wide, heavy shank with a high-profile cathedral-style gallery. The metal appears to be a white-toned alloy, potentially sterling silver, white gold, or platinum, exhibiting a noticeable aged patina and surface abrasions consistent with frequent wear. The metal surfaces show significant micro-scratching, dulling of the original high-polish finish, and some dark tarnish in the recessed areas, which may suggest a silver content. There are no visible hallmarks in this view, but the construction indicates a late 20th-century contemporary design, approximately 1980s to 1990s. The craftsmanship is substantial, favoring bold geometric lines over delicate filigree, characteristic of late-modern jewelry trends.
