Jewellery or jewelry consists of decorative items worn for personal adornment, such as brooches, rings, necklaces, earrings, pendants, bracelets, and cufflinks. Jewellery may be attached to the body or the clothes. From a western perspective, the term is restricted to durable ornaments, excluding flowers for example. For many centuries metal such as gold used in different carats from 21, 18, 12, 9 or even lower, often combined with gemstones, has been the normal material for jewellery, but other materials such as shells and other plant materials may be used.
