One of the most popular styles of necklaces, the pendant necklace consists of a chain with a single hanging ornament or charm. Pendants come in all shapes and sizes, from simple geometric shapes to intricate designs featuring gemstones, symbols, or even personal engravings. They can be a reflection of one’s personality or serve as a memento, such as a locket that holds a picture of a loved one or a pendant engraved with a meaningful date or phrase.
