Antique Art Deco Diamond Brooch Platinum 1.9ct Total

Born from the glamour of the 1920s, this magnificent antique Art Deco diamond bar brooch is exquisitely crafted in platinum, featuring a masterfully designed openwork gallery that showcases crisp geometric architecture and delicate millegrain edging. At its centre sits a bezel-set 0.30ct transitional-cut diamond, graded SI1 clarity - H colour, accompanied by an abundance of sparkling single-cut diamonds, bringing the total estimated diamond weight to an impressive 1.9 carats. 

Capturing the liberated spirit of the post-war era, the bar brooch evolved from a simple functional fastener into a radiant symbol of style, adorning the lapels and bodices of the era’s sophisticated “New Woman.” Its popularity rose alongside flapper fashion, as the brilliance of diamonds paired with the cool purity of platinum created the highly sought-after “white-on-white” aesthetic, a powerful expression of independence, and freedom during the Roaring Twenties. 

Presented in excellent condition, this spectacular diamond brooch epitomises the glamour and refined craftsmanship of the Art Deco period. A highly collectable and showstopping statement piece, it is perfect for adorning a lapel, scarf, or handbag once more, secured by a traditional trombone safety catch and 18ct gold pin on the reverse.
