The Art Deco jewelry period was from 1920 to about 1935. The extraordinary jewelry from this time features clean lines, colored gemstones and geometric shapes. Art Deco jewelry is still sought after today and it inspires modern jewelry design. During the time period, platinum was a popular metal, as you can see in our Estate Collection. Baguette diamonds were first introduced during the Art Deco period, as were the French and Asscher diamond cuts.
