What is a "necklace"?

A necklace is a type of jewelry that is worn around the neck. It typically consists of a chain or cord made of precious metal, such as gold or silver, that is adorned with decorative elements, such as beads, gemstones, or pendants. Necklaces come in a variety of styles, lengths, and designs, and can be worn for both casual and formal occasions. They have been worn by humans for thousands of years and have served as a form of personal adornment, cultural expression, and religious symbolism. Some necklaces are also considered to have protective or healing powers, depending on the beliefs of the wearer.
