The Art Deco era is considered the most creative of all design eras. The movement originated in Paris in the 1920s but its influence on jewelry and fashion design continues to this day. Art Deco jewelry pieces are usually symmetrical and embellished with intricate designs in platinum with enamel, pavé diamonds, rubies, sapphires, emeralds or other precious stones. Original Art Deco pieces are collector’s items. Specifically original pieces by Cartier, famous for its Art Deco designs fetch strong results at auctions.
