This necklace is called "Kay of the Heart." Beads like these were often worn by Zulu men and women as decoration and functioned as a form of communication. These particular necklaces were common gifts from a young girl to a favored lover. Margaret Walbridge, a Congregational missionary and the principle of Inanda Seminary (a boarding school for Zulu girls), collected this item during her time in South Africa in the 1920s and 30s. Originally from Russell, Kansas, Walbridge traveled extensively and used these beads in presentations meant to increase support for the seminary.
