Vintage Art Deco / Edwardian Diamond Ring in Original Jewelry Box

The item is an antique or vintage ring, likely an engagement or dress ring, set with a central square-cut diamond and accent diamonds. The metal appears to be white gold or platinum, exhibiting a silvery-white luster. The design is characteristic of the Art Deco or Edwardian era, featuring intricate filigree work and milgrain detailing, which suggests a period from the early 20th century, roughly 1910s to 1930s. The central stone is bezel-set within a square frame, and is flanked by shoulders that fan out, each adorned with smaller round brilliant-cut diamonds. The filigree work on the shoulders forms elegant curves and stylized floral or geometric motifs. The ring displays signs of age, including a visible patina on the metal and some minor wear consistent with its likely age. The small accent stones appear securely set, and the overall craftsmanship is indicative of quality, with detailed metalwork demonstrating fine jewelry manufacturing standards of its period. The ring is presented in a creme-colored, rectangular jewelry box, possibly Bakelite or an early plastic, with a hinged lid. The interior of the box features a light blue or possibly gray satin lining in the lid and a rich red velvet base with a slot for the ring. The lid's interior is marked with "BROUGHTON AT Drayton SAVANNAH", indicating a jeweler or boutique located in Savannah, which could aid in dating and provenance research.
