Indigenous Disk Beads in the Southern Southwest: Contemporary, Ethnographic, Ethnohistorical, and Archaeological Evidence

Abstract

Within the Phoenix Basin in southern Arizona, disk beads have long been highly valued. Remarkably, the Akimel O’Odham (i.e., Pima) and Pee Posh (i.e., Maricopa) still place great importance on them today. Similar beads were formed from shell, stone, and clay. The effort necessary to manufacture beads from these constituents varies, but beads made from different materials are often macroscopically indistinguishable. Furthermore, some raw materials had to be imported, while other constituents were locally available. These factors should have affected the value of different bead types, and ethnographic evidence shows that indigenous people have clearly defined preferences for attributes, including color and material. In particular, beads made from shell and turquoise are recognized as being most valuable. This paper presents archaeological, ethnohistorical, ethnographic, and contemporary data that show that small disk beads were a form of wealth that was employed in trade transactions.
