Native Americans in the Southwest have been wearing beaded jewelry for centuries. The beaded tradition is most closely associated with Santo Domingo Pueblo, known for creating beautiful shell and gemstone beads by hand. These beads are called “heishi,” which means “shell” in the Santo Domingo language Keres. Necklaces with similar bead styles have been found in the ancestral Puebloan sites Chaco Canyon and Mesa Verde, and heishi may be the oldest form of jewelry in New Mexico. Traditionally, heishi beads are smooth flat discs, but today the term is used to refer to any small beads that are strung together.
