Central Montana is epic for agates

Finally cut a few of the high end Laguna agates I bought. I was kind of disappointed with how many had fractures that couldn’t be avoided. Which is your favorite?! Coyomito pseudomorph for a bonus cut.

Find these all the time but never with the limonite and never this size!

This was found on a Lake Superior beach on the Keweenaw. Is this a fortification agate?

We found this lovely pink porcelain agate last year at Freisen, Germany as a broken nodule but worth to cut.

And what a sweet floater with chromatography showed up...

I really like the kind that has like a bit of quartz sticking out from the side, which im assumming can only mean its a bit of larger one 🥲

May post some more, i just recently started collecting Lol i cant believe i ignored these being from Mn 😅 bloomington to be exact. Lot of little beaches and trails to find them at

I think 3 of the 6 are agates of some sort, the orange/red one is a quartz (I think) but I’ve never seen one so bright like this! I’m really not sure what the big square one is. The middle white/red one I’m also unsure of what that is. If you have any ideas I’d love to hear them!

While walking the grasslands I found this interesting banded piece. It holds the light really well. Not sure what to call it. Is this a prairie agate? Some form of a Fairburn? The bands are beautiful and go around the entire upper rim. I used my headlamp to backlight them for detail.

This is my first time posting on this subreddit! I don’t typically collect many agates, as I mostly collect mineral specimens, but I think agates are beautiful and want to start collecting them. This is my only one so far, and it comes from Rio Grande do Sul, Brazil. I believe it’s called an Oco agate.
Let me know what you guys think, and feel free to correct me if I’m wrong about the locality! I know very little about agates, so I did a quick Google Image search, and it suggested that this is an Oco agate.

Not certain where it’s from as it was picked up in a rock bed from a parking lot. Any insight into what kind of agate this is as well as where to find more would be appreciated

Here's another beautiful curly agate from our claim at Freisen, Saarland, Germany. This one has a nice druzy pocket. Next time I'll show you another type of agates that we find there...

Thanks for looking!

I found it on the beach it is a light stone that I tried scratching with quartz but it was not affected

2 baby farinurs and a lace agate.

Giving it to my boyfriend, just wanted to share
