Is this from GA? If so one of the problems with it include pits that are not filled and also some of the bands have a layer of koalinite which causes them to separate. Have not found a suitable treatment. However I am looking into treating with sodium silicate and Citric acid to see if that works. If it does I would think rough tumbling first then seal. followed by the finishing the tumble. just a guess though

I wish I had an answer to your question, but I'm new to tumbling myself. I like rmf's suggestion of sealing it, but we'll see what the more knowledgeable folks have to say. That being said, I have to add a comment about the stunningly beautiful mess of a rock you have - both actually! I can see why you would like an answer as those are gorgeous! Sorry, I can't resist:

Looks like the kids were playing ball in the house again and were hoping no one would notice their “fix”!
Roman ruins seems like an apt name for those rocks, which look lovely just the way they are.

I absolutely love those! Both the agate and the name! I can understand being frustrated/heartbroken trying to polish these, but they still turned out beautiful the way they are. May I ask, is there a source where one can buy some of this rough material?

I like them too. If the agate patterns were broken up and healed 100% solid it would be my favorite agate. Unfortunately the broken / healed areas are a little soft, but I love it nonetheless.

This is really cool looking material. I wish I could find some of it as it would product excellent cabs for my wire wrapping hobby I think.
Your use of the word 'undercut' indicates that you understand the biggest problem with trying to get tumbles from these without seeing serious problems start to show up.
I am glad that you posted this batch though. Thank you!

I am glad that you posted this batch though. Thank you! The Ebay seller I bought it from has it listed on Ebay in lots of 1 pound up to 25 pounds or so. I think I bought 25 pounds for around $90. It's not real solid material, so it's frustrating with a lot of waste. But the fractured and re-cemented agates are cool enough that it might be worth the effort.

Nevadabill is right, those WOULD be great for wire wrapping just as they are !

You tumble what I call Roman ruins agate. Ok, it's really just Summerville lace agate that was fractured in the ground (a long time ago) and healed with limestone or some other softer mineral that undercuts when you tumble it. You can't tumble them to a uniform shine, but something about them reminds me of Roman ruins...

Nevadabill is right, those WOULD be great for wire wrapping just as they are ! Be careful. I've spent enough money recently on saws, a grinder, and a Genie. The last thing I need to do is buy more materials or equipment. But you do have me thinking...

Waterglass polymerizes to agate at low pH. Any low pH. Not just citric.
