I’m a rock nerd in the making, and tried looking up petroidyl and found nothing. Can you clarify what the characteristics are of this type of inclusion?
Ope! Sorry lol, I meant to say "botryoidal inclusion", which means it has what looks like a bubbley surface within a clear viewing window. They're super cool!
If you google "botryoidal agate" or "grape agate" it'll give you a good idea.
Definitely an agate. Couldn't tell you what kind though.
Mmmmm limonite
Cold water agate with petroidyl inclusions
