Jewellery is a personal ornament made from precious metals, gems, or other materials. It has been used for currency, wealth display, functional purposes like clasps, symbolism to show status or membership, protection through amulets, and artistic display in fashion. Modern jewellery commonly uses gold, silver, platinum, and other materials like glass, wood, shells, clay, and plastics. Jewellery takes many forms like necklaces, rings, bracelets, crowns, and serves various symbolic purposes in different cultures and time periods.
