Ancient Glass Bead Help

These are my clay beads and am happy to say I know absolutely nothing about them ant help would be greatly appreciated if anyone has any knowledge of these pieces.

 

The little flat disk shape is now called heishi & is associated with Native American jewellery. Are all beads that shape clay? The slender strand in the middle looks like a modern stringing job to me, but beads used could be old. The strand on the left you showed earlier must have been in that form for a while for the beads to have accommodated themselves one to another where the tips meet. That one feels oldest to me. I'm most intrigued by the strand on the right, which looks so much like stone. Are all strands long enough to go over the head without a clasp?

 

Hi thank you for looking yes they are all long enough apart from the clay one on far left.I think they were mixed when my friend got them and it looks like a bit of guesswork.Far right necklace seem to be Stone there’s wear where they meet each side.

 

Must weigh a ton?

 

Yes it’s a heavy one .

 

Also came with some hand carved Omije Beads .
