The Art Deco movement was an attempt to combine the harshness of mass production with the sensitivity of art and design. It was during this period that Coco Chanel introduced costume jewellery to complete the costume. Some era defining characteristics of costume jewellery in the Art Deco period include where free-flowing curves were replaced with a geometric and symmetrical theme and long pendants, bangle bracelets, cocktail rings, and elaborate accessory items such as cigarette cases and holders became desirable.
