A pendant necklace is a type of jewelry that consists of a small decorative piece, usually in the shape of a charm or a symbol, which hangs from a chain or cord around the neck. The term “pendant” refers to the main decorative element while "necklace" describes the overall design as it includes the chain or cord that holds the pendant. Pendant necklaces can be made out of various materials such as gold, silver, platinum, pearls, gemstones and even glass or plastic. They come in a wide range of styles from simple to elaborate designs, and are often worn for their symbolic meaning, personal significance or simply as an expression of fashion.
