They can be made of precious metalgemstones, clay, plastic, organic material, wood, base metal, just about anything. Beads are strung in a line for necklacesbracelets, and rings or suspended as pendants.

They are also strung or linked together for religious purposes such as a rosary or worry beads and can be sewn on fabric in patterns to embellish a garment.
