Please help me ID these stones

Hi everyone, I know I might be asking for the impossible, but any help would be appreciated! Not sure if it’s even worth taking them to the jeweller or not!

My googling is saying jet or treated black diamond for the one on the right but I’m having no luck with the one on the left? I’m soooo out of my depth.

The one on the right could also be highly polished onyx, or black jade, or less likely hematite ...

The one on the left reminds me of tiger's eye or black banded agate ...

Thanks Marymm! Tigers eye for the one on the left was my best guess too!

I have a photo of the underneath of the ring of the right if that helps eliminate any options…

Another option besides the ones marymm stated is black spinel.
