✅ SOLVED What is this?

[Axel's Nature's Best]

Hello! I have trouble identifying this crystal, I would appreciate any guesses!

It is rather smooth to the touch and has a vaguely diamond-shaped pattern in the middle that starts from a grayish blue and turns into a darker gray. There is also small bits of brown and white

The luster is vitreous I assume? It looks rather glass-like. Correct me if I'm wrong!

The piece with the banding looks like agate. I’m not sure about the other one.

They're both from the same piece! Just the back and front. But Agate is a good guess, I will see if I can test it in any way!

That looks like a sliced and polished banded agate nodule.
