The creation and use of beads goes back thousands of years. Beads have been made out of many things. For example: stone, teeth, shells, pearls, copper, glass, and bone. Many used the local resources to find and make their beads, but trade networks provided a larger array of materials for people to use. The Science Museum of Minnesota has a large collection of artifacts that contain beadwork. The information and images below are selected items from our accessioned collections.
