Wild Bill that is real cool. Been watching some YouTube videos on those. They look nice. Good for you!

I grew up in Lake Superior agate country. My younger brother has buckets and buckets full. He had access to a few local gravel pits. I don't have many pics - found the big one while spring turkey hunting and walking across a plowed field. Happened to kick it loose and noticed the agate color.

ChatGPT is telling me it’s either a chalcedony nodule or a weathered agate fragment, not a true Fairburn.
Still cool to me.
Guess I’ll have to keep looking!

Agates are chalcedony.

Agates are chalcedony.

News to me. I'm not a geologist. I just like rocks that look cool to me, ha.

This is a cool thread. Love rocks but know next to nothing about them. Bought a set of screens to sift through local rivers. It’s just a fun way to spend a few hours if the fish aren’t biting. Our local desert has some fascinating petrified wood. My favorite is obsidian.

If you hold a agate up to the sun you should see a halo/glow from the sun around the edge of the rock so you know its a agate.

They are cryptocrystalline or microcrystalline quartz aka Chalcedony.

all agates are chalcedony but not all chalcedony is agate

All elk are deer but not all deer are elk.
