Help identifying rocks from Arizona

[kmonti33]

Took my first rockhounding trip ever to find fire agate (which I did), but also managed to find some other interesting pieces I was hoping someone could help me identify. I think the first one is a thunder egg? Not sure what the banded one is. Also if the first one is a thunder egg, what should I do with it or should I cut it or finish it somehow?

Left one looks like quartz with some kinda coating. Unsure of the other one.

Quartz and basalt.

For anybody here who doesn't already know, a thunder-egg is a "filled" (no longer hollow) geode. The "egg" part of the name comes from the stone's shape.

To my eye, the stone you think might be a thunder-egg has one of the right exterior looks to be a geode or thunder-egg. To find out, without smashing it, you'll need to take it to a "rock shop" that has a stone-saw for sawing geodes in half. The shop typically charges a moderate fee for doing that work.
