Mostly quartz as agate is but I don't think an agate. Likely segregation in a SiO2 rich environment. Just an opinion.

it is interesting looking that's for sure, not sure about it being an agate though. Where did you find it?

Looks like a metamorphic sedimentary rock. I'd say it's a quartz agate now or considered a chunk of marble.

It could be an agate. I have one that looks just like that that I picked up in Washington along with a bunch of jasper and other agates
