HELP! Unknown Rock

[CowboyTones]

This was found in Southwestern South Dakota near the Black Hills. Can anyone tell me what type of rock it is? Thanks in advance.

It's an agate, nice one, if you want to clean it up better use super iron out, (Wear eye and hand protection and do it outside) it works really well on quartz, nice find.

Welcome to the forum.

Nice one!!’ It looks like a prairie agate to me.

Were you at the buffalo gap national grasslands by chance? Looks similar to things we have found there.

I wonder if that could be Mozarkite rather than an agate. Just dont see typical banding patterns like in an agate

Awesome! Thanks for the response Steve. I will have to try that.
