Stone or wood or??

Was told petrified wood then stone. Thoughts?

 

Looks like agate. https://www.google.com/search?q=aga...XCtVkKHT04ArgQ_AUoAXoECA8QAw&biw=1386&bih=739

 

Petrified wood is stone, "petrified" comes from a Latin term meaning "turned to stone."

But this doesn't look like petrified wood, to me, but more like a slice of a geode.

Better wait, though, for someone who specializes in that area. My experience comes mainly through a brother-in-law rock hound/collector/jewelry guy.

 

To me it looks hard to tell from that view.....looks more like a ceramic creation around the edges in particular, but maybe my eyes just aren't adjusting to the perspective!!

 

Maybe ask on a gem and stone ID site if no one on here knows?. I’m on one on FB that I use from time to time on the rare occasions I draw a blank here

 

The answer was in post #2.

 

Thanks again all!!!

 

I'd agree, slice from a geode; so the stone would be agate. During the formation of such things, the agate material is laid down in layers within a hollow in the rock, and often in geode slices one can see the layers, as with OP's example.
I'd go further, and note the outer brown stone visible on one outer edge; this would pretty much confirm the ID as being from the type of geode often called a "thunder-egg."
