Costume jewellery is made from less valuable materials. However, jewellery can and has been made out of almost every kind of material.

Jewellery in various forms has been made and worn by both sexes in every human culture, on every inhabited continent.

Some cultures have a practice of keeping large amounts
of wealth stored in the form of jewellery.
