Gold-Tone Solitaire Interlocked Bypass Shank Ring

This item is a fashion ring featuring a yellow gold-toned metal finish and a single circular-cut colorless stone. The design follows a bypass or 'interlocking' style, where the shoulders of the shank curve around the central setting in a twisted, ribbon-like manner. The central stone is a brilliant-cut synthetic material, likely cubic zirconia or glass, secured by four prominent prongs integrated into the twisting metalwork. The ring's band is relatively narrow and tapers towards the bottom. Physically, the item shows significant signs of wear and age; there is visible pitting and oxidation on the metal surface, particularly where the gold plating has worn away to reveal a silvery base metal underneath. This indicates it is likely a costume jewelry piece made from a base metal such as brass or nickel. The stone exhibits several surface scratches and lacks the sharp internal fire of a genuine diamond, consistent with faceted glass or low-grade synthetic stimulants. No hallmarks or maker's marks are visible on the outer surfaces. Considering the design aesthetic and construction quality, it likely dates from the late 20th century, specifically the 1980s or 1990s, mimicking popular fine jewelry trends of that era.
