Three strands from an Africa Trader who gets things from Djenne region, he did not know the material, but I think it is faience. Can anyone confirm? From Egypt, Persia, or? How old?

Disclosure, I AM a dealer, but not trolling for buyers, just want to describe things accurately. Usually they know far more than I do, or I can crib information from my "betters" online, but can't find this bead style anywhere.

For reference, Beads mostly 8x10 to 15x17mm, very wide center holes.

Please click on the "related link" to see the beads - I think I've got this fixed now! Thanks.
