The Pomo are an indigenous people of California. The historical Pomo territory in Northern California was large, bordered by the Pacific Coast to the west, extending inland to Clear Lake, and mainly between Cleone and Duncans Point. They are known for their mastery of basketweaving from a variety of natural materials, including swamp canes, saguaro cactuses, rye grass, black ash, willow shoots, sedge roots, the bark of redbud, the root of bulrush or blackroot, the root of the gray pine, willow shoots and roots, sometimes bracken fern and a variety of colorful bird feathers, abalone and other types of shells, magnesite beads and sometimes glass beads. The Pomo also crafted elaborate jewelry made from abalone and clamshells. Assembled during the winter, during the summer the Pomo would travel from various sites along the coast where they would fish and gather all of their materials needed to create their jewelry.
According to the records at the National Museum of the American Indian, this hairpin made by a Native American artist from the Pomo culture was collected by Californian basket collector and dealer Grace Nicholson, who later sold it to the museum.
