A decorative style for jewelry developed in the 1920-30's in which the form is in abstract geometric shapes, produced with great precision, and the articles generally are smooth and highly polished. Such jewelry was a development of the Art Deco style, and the designers who worked in this style included Georges Fouquet, Raymond Templier, and Wiven Nilsson.
