What is a "charm"?

A charm is a small decorative item, often worn on a bracelet or necklace, that is believed to bring good luck or ward off evil. It can also serve as a reminder of a special occasion or person. Charms can be made of a variety of materials, including precious metals, gemstones, and enamel, and can take on many shapes and designs. Some popular charm designs include animals, hearts, letters, and symbols, such as a four-leaf clover or a horseshoe. They can be worn individually or in groups, and are often given as gifts for birthdays, graduations, or other special events.
