From Ghana 

“Waist beads are an age old African tradition and are worn for vast reasons and purposes to celebrate femininity, healing, spirituality, power, balancing, attracting and keeping a mate, rites of passage, rejuvenation, initiations, first menses, energy, and body shaping. African women have traditionally worn waist beads beneath their clothing placed beneath the belly button and can be single or multiple strands. Other cultures proudly display the beads over their clothes or on bare midriffs. The art of adorning ones self has been practiced since the beginning of time. "
