African Glass trade beads?

im pretty sure thats what they are. I got them at an amazing high end estate sale in Maryland. I got a really nice African tribal collection that no one else was interested in. I was in shock for about a week after realizing how awesome I did. Im sure that they are old and not sure of tribe or even if it was Africa. I have seen the 7 African Powers necklace but this one is in groups of 6 and 2 of the groups 1 red and 1 orange have only 5 not sure if broke or what. A ny help would be awesome.

 

Agree, the beads look like the ones on the Seven African Powers necklaces. Those necklaces are important in the Santería religion of Cuba and Puerto Rico. The colours represent the different Orishas.
I don't know if they can be personalised with just the colours of some Orishas. If so, this could be a presonalised one.
