The Art Deco style emerged during a World’s fair exhibited in Paris, France in 1925. Besides jewelry items, cars, architecture, paintings and other forms of art in this period can easily be identified because of their exclusive qualities. The emergence of white gold is a characteristic of this period, and it was mainly brought in as an affordable alternative to platinum. Unconventional diamond cuts became popular during this period like the Asscher cut, Cushion cut and Transitional cut and the Old European Cut diamonds. The key difference between Art nouveau designs and Art Deco ones is in the geometric cuts of the latter, with more symmetry and a lot less flow. The Art Deco engagement rings, wedding bands, and other jewelry were mainly crafted with 10K or 18K white gold.
