ANTIQUE ART DECO Tiffany & Co Brooch 18k White Gold 2ct Diamond & 0.5ct Sapphire

Presented for auction is a museum-quality, original Art Deco era (circa 1920s) bar brooch by the legendary American jewelry house, Tiffany & Co. The Art Deco period was characterized by a departure from the flowing lines of the Art Nouveau era, embracing instead geometric elegance, elongated forms, and the brilliant contrast of diamonds against vibrant colored gemstones. This piece exemplifies the era’s finest craftsmanship, utilizing 18-karat white gold—a highly sought-after metallurgical innovation of the 1920s designed to emulate the look of platinum while offering exceptional durability for intricate milgrain and open-work settings. The elongated, tapered bar design was historically worn to secure fine silk scarves or elegantly pinned to the lapel of a drop-waist dress, representing the zenith of Roaring Twenties high-society fashion.
