A decorative style that originated in France in the 1920’s and 1930’s in protest against the Art Nouveau Style and later art movements. It is also called art moderne, Art Deco was characterized by linear decorative designs that were reminiscent of modern technology. It emphasized long, thin forms, curved surfaces and geometric patterns in order to symbolize the expanse of the machine age. It emphasises abstraction, distortion, and simplification by use of geometric shapes and intense colours.

The jewellery pieces representing this period often contain black, resin based enamel and stones such as Swarovski crystal.
