This is a silver ring from the Tuareg people. Tuareg accessories often use nickel alloy as a silver substitute, but this one is made of silver. The Tuareg are an ethnic group living in Niger, Algeria, Mali, and Libya, known as the "Blue People" for their blue turbans and clothing, and they are a nomadic desert-traveling people. The origin of this ring is Mali.
