I have no clue what they are...but if they are rare, then tumbling them would be akin to tumbling Fairburn Agates. Some people refuse to do anything with them and want to leave them in they're natural state...other people have no issues with tumbling them. I hope you find out what they are. I would tumble them though.

Deep down I want to tumble them...maybe I'll just hold of for a couple years lol One of the best pieces of advice I've ever received in my life was hearing the phrase, "You can't unring a bell." From a philosophical standpoint, that is an amazing phrase. In this case, it's like saying you can't uncut a rock...nor can you un-tumble a rock. Don't pull the trigger until you're sure you're sure. That rock has waited this long...it can wait some more.

Not sure what you have and I grew up on the north shore of Lake Superior. I would not tumble the first one because you will grind off the fine detail and ridges. The second one is too cracked and fractured to tumble with those open voids. Post them up in the rock ID section and lets see if we can find out what they are for you. I wonder how hard the first one is but I do not want to ask you to test it as you might damage the pattern.

Son Of Beach The first three are chert and they will tumble fine. Not sure about the last two. looks like quartz and malachite or quartz and greenstone. Either way don't tumble it. Find out how hard the green is. the quartz in it is cracked and probably will not tumble well. If you can scratch the green with a knife it could be either of the above green colored stones I mentioned.

As for the blue/green, I know I shouldn't have, but I threw it in the tumbler a couple days ago, too curious to see what happens. If it holds it should be an excellent color.

Just picked up this Montana Agate Geode Thunder Egg for a couple bucks and I'm already wondering how to ruin it. I don't own a flat lap...no way of polishing the face. It looks like it could be solid the whole way thru...think its worth a shot to tumble?
I guess I could hand polish it...

That does not appear to be Montana Agate. It looks a lot like a Choya Geode half to me.

Edit: I realize now that the "geode" shape probably has a lot to do with it being a geode

Once again, my first reaction is to slab it and cab it! LOL
This looks like it's another one that would look amazing tumbled...if it held up. I'll be curious to read what more experienced tumblers think about whether it would survive.

Here are the results of these stones Really happy with the banded chert Slightly bummed about the blue one, the colors didn't pop the way I thought they would

Banded chert is one of the best tumbling rocks you will find in Michigan. I'll share a photo sometime of the pieces I have found and tumbled. They get very shiny!
