Vintage Multi-Gemstone & Diamond Gold Ring

This is a vintage gold ring featuring a prominent central diamond flanked by multiple smaller gemstones, primarily rubies and what appear to be yellow diamonds or sapphires. The ring's design is complex, appearing to be composed of two or more bands fused together or designed to intertwine. The main body of the ring, particularly the upper sections around the shoulders, has a textured, darkened, or patinated surface, possibly an intentional antique finish or an oxidized treatment, which contrasts sharply with the polished gold elements that hold the gemstones. The central stone is a round brilliant cut diamond, approximately 0.5 to 0.75 carats, set in a bezel or semi-bezel style within a polished gold band. On either side of the central diamond, in the contiguous polished gold band, are smaller round faceted gemstones. On one side, there are at least two discernible red stones (likely rubies), and on the other, two lighter, possibly yellow or colorless stones. The darker, textured gold portions of the ring also feature smaller, dark stones, possibly black diamonds or darkened sapphires, set into the surface, adding to the intricate detailing. The overall construction suggests a substantial piece of jewelry, with significant weight. The craftsmanship appears to be detailed, indicating a quality piece, possibly handmade or custom-designed given its unique aesthetic. The contrasting textures and colors give it a distinctive appearance, suggesting an Art Deco or Mid-Century Modern influence, or possibly a custom piece from a later period drawing on these styles. The item is currently placed within a cream-colored velvet or satin-lined jewelry box, which has a reddish-brown exterior with gold-toned trim, suggesting it is a kept item, possibly for presentation or safe storage. No visible damage or major wear is evident from the provided images, though a full assessment would require closer inspection.
