Tuareg Leather and Silver Tcherot Amulet, decorated with raised buttons and etching, in 2 pieces, from Mali or Mauritania.
Amulet measures approximately 3.1" (80mm) tall and and 1.6" (41mm) at narrowest width. A nice size for a focal pendant, soft to the touch and still substantial.
Tcherot typically contain small objects with amulet properties and carefully folded magical formulas as well as verses from the Koran, all designed to protect and strengthen the wearer or to ensure her fertility. A Tuareg girl receives her first Tcherot from her mother at the age of seventeen. (from the book "African Beads, Jewels of a Continent" by Evelyn Simak)
