Thanks for your answer!
I thought there are not true bodom, there are glass powder beads made in Africa. Where? I don't know, they come perhaps from the same country than the another glass powder beads that are from one color. I called them "modern Bodom", because they want maybe imitated bodom. But I do not know if they come from Ghana. But one of them is an islamic: that is often the surprise in these necklaces: the black one with white stripes near the big red bead!!. Once, I discovered a Morfia bead in a necklace with beads without any value!! it is the surprise of the researcher of beads in Africa!!!!
