Antique British 9ct Rose Gold Bangle with Full Hallmarks

This item is a slender, circular bangle crafted from 9-carat rose gold, characterized by its warm, coppery hue. The focus of the image is the interior of the band, which features a series of deeply struck British hallmarks within rectangular and rounded cartouches. The marks include '9' and '.375' indicating gold purity, an anchor symbol representing the Birmingham Assay Office, and a stylistic date letter 'b' likely corresponding to the late Victorian or early Edwardian era (circa 1900-1901). There is also a partial maker's mark consisting of initials. Physically, the bangle shows signs of age-appropriate wear including fine surface scratches, minor indentations, and a soft patina. The construction is solid yet refined, indicative of late 19th or early 20th-century jewelry craftsmanship. The interior surface appears slightly uneven around the hallmarks, which were hand-stamped. No major repairs or structural breaks are visible in this specific view, though the gold shows the characteristic light oxidation of antique rose gold alloys.
