A necklace is a piece of jewelry worn around the neck, often made from a variety of materials such as metal, beads, gemstones, or leather. Necklaces can range widely in style, from delicate chains with simple pendants to bold statement pieces adorned with intricate designs. They are commonly used to enhance an outfit, express personal style, or symbolize meaningful connections like love or friendship. Necklaces can be adjustable, allowing for different lengths, and often feature clasps or closures for secure wearing.
