The document discusses different types of jewellery. It defines jewellery as small decorative items worn for personal adornment such as rings, necklaces, and bracelets. Jewellery can be made from gemstones, precious metals, beads, and shells. There are four main types of jewellery: fine jewellery which is made of solid gold and genuine stones; semi-fine jewellery which uses gold plating and genuine stones; bridge jewellery which features semi-precious gemstones; and costume jewellery which is mass produced from inexpensive materials like rhinestones and base metals.
