The first one, the green one, really looks to be a lampworked bead. I
don't recall if you said how large the bead is, but if it's anything
larger than about 12 mm long, it most likely is a lampworked bead.
You might try doing a google search on lampworking sites to see if
anyone has something similar. You may be able to commission a similar
piece. You just never know if you don't ask.
