Earrings, ornaments made of metal or jade and worn on earlobes. Earrings can be made of metal, plastic, glass, precious stones and other materials. Some are circular, some are vertical, and some are granular. The weight and size of the earrings are limited by the human body's tolerance. Some people who are used to wearing heavy earrings will find that the ear beads and ear holes are elongated after wearing them for a long time.
