I would love if someone could tell me anything about this necklace. I really like the stones but not sure if its a banded carnelian or jasper or something else entirely.

The center bead is also a mystery to me. It looks like a nut or possibly wood? Then there's these strange looking semi-transparent swirl amber colored beads that look and feel like glass but are actually bakelite according to "the simichrome test"

Anyway if anyone knows what the stones and center bead might be please share your opinions thanks
