Les styles de bagues de fiançailles de l'époque étaient inspirés du cubisme, Modernisme et futurisme. Le thème de l'Art Déco était la géométrie, couleurs vives, et la symétrie, mais en particulier dans les bijoux, les bagues de fiançailles reflétaient l'époque avec un look géométrique épuré.
The engagement ring styles were also influenced by two design periods that preceded Art Deco—the Art Nouveau and the Edwardian era.
The early Art Deco engagement rings adopted some of decorative and flowery accents of Art Nouveau in sleeker designs, like this antique art nouveau engagement ring, but later replaced them with harshly geometric and symmetrical motifs.
The Edwardian style influenced Art Deco jewelry designers in the use of platinum and diamond on engagement rings, as this antique Edwardian diamond daisy ring shows. In comparison with Edwardian rings, Art Deco engagement rings were less conservative and more geometric. In its structure, the 1920s engagement rings had straight lines and distinct geometric shapes, opposed to Edwardian rings’ curved lines and nature-inspired motifs.
