You could call them rondelle beads, this is the common terminology for beads of this shape. The one bead in the middle with the blue dots is Venetian, late 1800's early 1900's. The rest are probably Czech with a variety of ages I would say anywhere from the mid 1900's up to today
"lenticular" describes the "lentil"or "lens" shape- likely made by the Bapterosses company in France- and see Floor's research!
The white beads ar indeed Prosser beads, most likely made in Briare, France. That includes the lentil shapes, the tubular white ones (tile beads) and the speckled white with green ones. The bog white one with the stripe is also a typical French Prosser bead.

Thank you very much,that is helpful. These were purchased in Africa during the 1960's. I inherited a huge collection from an old family friend when she passed.
