Perhaps you could tell us roughly where u found it?
Have you tried to scratch it with a knife blade?
Looks agatey to me too but diagnostics are helpful.

I did scratch test it and it did not scratch.
Found in a pile of rocks that the city uses to put in around sewer pipes and sewer vaults.
This was in southwest Wisconsin, but the origin of the rocks are unknown.
I had a previous post with some finds I had last week and the first photo was found in the same rock pile.

Looks like many of the chert/quartz mixes I am finding in Central WI. Very nice color and pattern on yours.
A lot of Central WI rocks are used for gravel mixes. I was looking at a modular home display recently. The mixed landscape rock there contained agates, fossil corals and lots of banded cherts.

Maybe it's a Rhyolite. That first photo resembles Wonderstone.

Definitely not a Laker.
Identical to what they call a Prairie Agate in my neck of the woods, which is South Dakota.

Wonder stone is a trade name given to stones collected from wonderstone mountain outside of Fallon Nevada. I am told there are similar deposits in Utah and definitely one called rock candy in New Mexico. As for Salton sea, where should I go look? All I know of is obsidian. |

Another vote for Prairie agate aka "Lakota agate."

I think these are also AKA Fairburn agates. But a rose is a rose. Nice stone!

It does look somewhat like a prarie agate but not quite, definitely not a Fairburn? I have found both , looks like the agate chart mixes I find around Colorado, good banding should polish up nice, always a nice find when you pick them yourself!

There is some unpublished science indicates prairie = fairburn |

Shotgunner I can believe that Fairborn's and Teepees are pretty closely related. But the rocks that I know as prairie agates are another thing altogether. I think the biggest confounding of the whole agate story here in South Dakota is that some unserious people want to make money off the unsuspecting and throw a bunch of BS in the sales pitch that we have to wade through. I know that you are pretty serious about these rocks so I figured you would have some basis for your statement.
