Detail of a necklace made by the Chippewa people. It consists of 18 teeth interspersed with red glas beads on a cloth band. The teeth are taken from domestic horses, mainly at the age of 10. A brown discolouring of the teeth is created by contact with human skin and indicates that the necklace has been used.
