The Tuareg are a nomadic tribe which live in and about Sahara Desert region of Africa. They are reknowned Silversmiths who also make quality one of a kind leather goods. Traditionally, Tuareg craft in Silver because it is believed to have protective qualities. The Silver used traditionally is not Sterling Silver as we are accustomed to in Western world, but a Nickel Silver found in region where tribe lives.
There are different cross designs representing villages throughout Niger, Africa. It is believed crosses relate back to ancient times before Tuareg were influenced by Islam; a time when Christianity heavily influenced people of region. Originally, when a male child reached puberty, crosses were passed down from father to son to show village he was from. It is said that father would say to son: "My son, I give you four corners of world, because one cannot know where one will die".
Today, crosses are used as adornment by men and women.
