My husband makes lampwork beads and loves glass. He was able to look at the beads in good light today. He saw bubbles on the inside and wanted to pass along that he thought it was a great suggestion on the forum to look for bubbles.
He thinks the beads are glass. He said they could be carved, but still is not 100% sure. He is still working on that part.
Thanks again for all the help and info!
