It's clear to see that these beads have been drilled from end to end.
Glass is usually wound on a mandrill so I would have to say these are stone.
The blue ones could be glass pieces that have been shaped and drilled but I haven't seen drilled glass except for German marbles.
I think your beads are prob stone of some sort. Look for air bubbles too. That is a sure sign of glass.
See ya at the forum
