Dear Jamey... as I said, all these beads in this post were purchased on one necklace from an inexperienced African bead trader. My conversation with Haje today indicated that it is getting harder to get beads in Africa. He was interested that I had a full necklace of second generation Nueva Cadiz because he had a client who wanted them and he was worried about how hard it was to find them in Africa. I still can't believe they are early Islamic! What about the black residue in the perforations? What is your thoughts on the other beads, Sir Non-Bead God.
