i can see small cylindrical "prosser" moulded beads of opaque white glass, and a bunch of white carved Turkish Meerschaum beads - that's what was often also carved into the bowls of tobacco pipes.The beads may not be terribly old-

My picture shows 2 turkish necklaces of beads like yours and some loose carved beads of Meerschaum from Tanzania that have been waxed and polished-

(trying to send the image but my system doesn't like to send it so will try again separately- it doesn't believe me when i reduce the image size... )
