The exact spot where the beaded necklaces may have came from is unknown but the necklaces made by the Samburu look just like this.

The beaded necklace was used for an Emurature, which is a ceremony that is for Samburu boys that want to become warriors or Imurran. It is fashionable to wear with bright red material. 

They can be used as wedding gifts and for the bride to wear as jewelry. The beads can be traded by Africans.

The beaded necklace might have also come from the Swahili tribe. They made their bead necklaces from clay, stones, twigs, eggshells, ivory, and bones. The bead necklaces pictured here looks just like the one that the Swahili tribe makes.
