Hello, I inherited a very large collection of mostly African trade beads. However, I am having a hard time identifying these carved beads. They are lightweight, definitely not glass or stone. I believe they may be made of wood. The lady who owned them lived abroad with her husband as he was an employee of World Vision and she was an employee of the US Embassy. The only places I know they lived for sure was Africa (Ivory Coast, I believe) and the Philippines. Any help with identifying these would be appreciated.
