Costume jewelry (also called trinkets, fashion jewelry, junk jewelry, fake jewelry, or fallalery) is jewelry manufactured as ornamentation to complement a particular fashionable costume or garment. Costume jewelry came into being in the 1930s as a cheap, disposable accessory meant to be worn with a specific outfit. It was intended to be fashionable for a short period of time, outdate itself, and then be repurchased to fit with a new outfit or new fashion style. Its main use is in fashion, as opposed to 'real' (fine) jewelry which may be regarded primarily as collectibles, keepsakes, or investments. Costume jewelry is made of less valuable materials including base metals, glass, plastic, and synthetic stones; in place of more valuable materials such as precious metals and gems.
