AI-assisted summary
Description from the seller
Art Deco platinum ring, circa 1930, centred with an octagonal step cut sapphire of deep velvety blue, held within a crisp geometric frame. The plaque head is lined with 50 rose cut diamonds in graduated rows, finished with fine millegrain and a light openwork gallery. Diamond set shoulders taper to a slender band, giving a clean line on the hand. A compact, architectural jewel that still feels quietly modern, in good condition for its age.

Style
Art Deco - Art Deco is an eclectic artistic and design style which had its origins in Paris in the first decades of the 20th century. The style originated in the 1920s and continued to be employed until after World War II. The term "art deco" first saw wide use after an exhibition in 1966, referring to the 1925 Exposition Internationale des Arts Décoratifs et Industriels Modernes that was the culmination of high-end style modern in Paris. Led by the best designers in the decorative arts such as fashion, and interior design, Art Deco affected all areas of design throughout the 1920s and 1930s, including architecture and industrial design, as well as the visual arts such as painting, the graphic arts and film. At the time, this style was seen as elegant, glamorous, functional and modern.
