Costume jewelry was originally created as theater props, and was large, fake, and flashy so it could be seen from the stage. In the 1930s Costume jewelry became an inexpensive accessory, to be worn once with a particular outfit. It was made to be fashionable and trendy for a short period of time.

Costume jewelry is made out of base metals, glass, plastic, and faux gemstones instead of precious metals and gemstones, to keep the cost down. Costume jewelry can be found in vintage stores and retail stores.
