How old is vintage costume jewelry?

Vintage costume jewelry refers to costume jewelry that is 20 to 80 years old. Jewelry, costume or otherwise, that is 100 years old is referred to as antique. The big design fair in Paris in 1900 inspired jewelers to work with inexpensive materials, and Gabrielle "Coco" Chanel and others helped popularize costume jewelry during the 1920s. The roots of costume jewelry, however, took shape at least as far back as the 18th century, when paste jewelry that featured hand-cut glass instead of gemstones first emerged.
