Art Deco Platinum Diamond & Onyx Double Clip Brooch Charlton & Co.

Charlton & Co. was founded in 1909 in New York City by John W. Charlton. He was an experienced jeweler who established the firm on Fifth Avenue before bringing in a partner Robert S. Chapin and adopting the name Charlton & Co. After Charlton’s retirement in 1919, the company came under the leadership of James Todd and Grant A. Peacock, who guided it through its most celebrated years. During the 1920s, Charlton & Co. became one of America’s leading Art Deco jewelers, thanks in large part to the influence of French designer Maurice Duvalet, whose work translated the latest Parisian fashions into creations for the American market. The firm’s bold geometric designs, exceptional diamond jewelry, and strong connections to leading French workshops helped define the elegance and innovation of the Art Deco era. Today, Charlton & Co. jewelry remains highly prized by collectors, museums, and auction houses because of its rarity, craftsmanship, and historical importance. Many surviving pieces showcase the finest materials available at the time, including platinum, diamonds, emeralds, rubies, sapphires, and onyx, crafted with meticulous attention to detail. Collectors particularly value Charlton’s Art Deco creations for their distinctive design language, which combines American luxury with European sophistication. As relatively few pieces have survived compared with those of larger jewelry houses, authentic Charlton & Co. jewels often command strong prices at auction. Their enduring appeal reflects both the timeless beauty of Art Deco design and the firm’s reputation as one of the most influential American jewelers of the early twentieth century.
