Dannoh - your pictures are too blurry to tell for sure, but the ones that appear to have glossier surfaces when compared to the natural amber - are probably phenolic resin beads. The other possibilities are casein, celluloid, and polyester. In other words, almost impossible to say which plastic without direct examination.
