Unknown Rock found in Western Colorado stream a few years back. Agatized something?

Agatized coral maybe?

[Hal Gorges]

Doesn’t look like coral.How big is it...I like.

[atlatlat]

a bit over an inch diameter, roughly half inch thick. It's a very wild looking stone

[tomclark]

agate (banded?) of some sort... nice piece! cryptocrystalline quartz.

I don’t think it’s a fulgurite but has some of the attributes. I’d brought home too !
