After a quick Google search, it appears that these dolls closely resemble Ndebele women, an ethnic group in South Africa. Some time ago, the Ndebele women wore rings around their arms, legs, and neck upon marriage to show her loyalty to her husband. They were also symbols of wealth. The wealthier a woman's husband was, the more rings she had. She was only allowed to remove the rings upon her death. It is no longer a common practice to wear these rings permanently, but the history is remarkable.
These tall beaded African dolls were handcrafted.
