Art Deco jewelry, popular from the 1920s to the late 1930s, is known for its bold, geometric designs and modern aesthetic, reflecting the glamour and innovation of the Jazz Age. This period embraced symmetry, clean lines, and striking contrasts, often incorporating motifs inspired by ancient Egypt, Asia, and industrial architecture. Platinum and white gold were widely used, frequently set with diamonds, sapphires, emeralds, and onyx to create high-contrast, eye-catching pieces. Calibré-cut gemstones—precisely cut to fit snugly into a design—were a signature technique. Art Deco also embraced new technologies and materials, like bakelite and rock crystal, highlighting the era’s forward-thinking spirit. This style continues to be celebrated for its sleek sophistication and timeless appeal.
