Jewellery (or jewelry) refers to any clothing accessory that is worn as a decoration.
In itself, jewellery has no other purpose than to look attractive. However, it is often added to items that have a practical use. Items such as belts and handbags are mainly accessories but may be decorated. A broach, often worn to keep a cloak closed, could be highly decorated with jewels.
Necklaces, finger rings and earrings are the most usual kinds of jewellery.
