Beads are meant to copy various classic Mauritanian bead materials:
Amber, coral, carnelian, amazonite and the now so valuable "Suleymani" agates!

No surprise to see plastic materials worn all over Mauritania these days, since the country was basically cleared of all their authentic bead materials.

Neo-colonialism by means of money, rather than militairy.

A terrible development we are all guilty of, I guess - from buyers big and small to museums and collectors!
