Costume jewellery differs from fine jewellery mainly in being less pretentious and less expensive. Costume jewellery encompasses some precious metals, especially silver, and also beads, paste gems, and semi-precious stones.
People wear costume jewellery for the look and the fun. It's never an investment or a status symbol. Costume jewellery is often flashy, sometimes tasteful, and can be appealing and attractive, but people never wear it to show off their wealth. Look cool and have fun in costume jewellery.
