The Deco Diamond Bar: A 1920s Style Statement

A paragon of Art Deco sophistication, this bar brooch, circa 1920, presents a harmonious blend of platinum and 18K white gold. Its abstract motifs and precise geometrical forms echo the era's departure from organic to the decisively modern. Adorned with 67 diamonds, including a central old brilliant cut of approximately 0.42ct, complemented by old mine cuts and rose cut diamonds, it captures the essence of the Roaring Twenties—elegant, glamorous, yet functional. A single onyx accentuates its bold, decorative statement, cementing its status as a collectible piece of that opulent epoch.

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.

Style specifics
Abstract motives and geometrical forms are quite typical for the Art Deco period. Art Deco moved away from the soft pastels and organic forms of its style predecessor, Art Nouveau, and embraced influences from many different styles and movements of the early 20th century, including Neoclassical, Constructivism, Cubism, Modernism, and Futurism. Its popularity peaked in Europe during the Roaring Twenties and continued strongly in the United States through the 1930s. Although many design movements have political or philosophical roots or intentions, Art Deco was purely decorative.
