Rocks to Avoid Tumbling

Do you ever wonder which rocks you should pick up on the beach and which ones you should leave behind? In this video, I'll show you how I decide which rocks would probably not do well in a rock tumbler. Then I'll tumble those poor choices so you can see how rocks like those will turn out.

It was funny that as I watched you reveal the tumbled rocks, I thought that even with the pitting and undercutting, that many of them looked great to me. Then when you pulled in the ones you showed as examples of great tumbling results, it was clear what you look for in your final product and the other ones clearly didn't measure up. Great video.

[@MichiganRocks]

Yeah, I like my rocks REALLY shiny.

[@guard13007]

Exact same reaction. I was like "Okay, he's just too picky." until I saw the good rocks.

[@Silvercanth]

That's how people that get into art and stuff fall for the Dunning-Kruger effect (if you don't know what that is I'd very much suggest looking it up. It's fascinating and I'd be surprised if it doesn't make you recall people you've met in your life) but you are clearly too smart for that, good job. I had the exact same reaction you did. :P

[@MichiganRocks]

@@Silvercanth I had to look that one up. I can think of many things in my life where as soon as I started learning about it, I realized that the subject was much, much deeper than I realized before.

[@Silvercanth]

@@MichiganRocks Any day where you learn something is a successful day. I'm glad to have played a part in you learning something neat.

[@samh1403]

I thought those rocks were looking pretty great out of the lot-o... until you compared them to your typical insanely perfect rocks. It really helped back up you're reasoning for being so picky about the rocks you start with and you're entire process. I'm a big time believer in your methods. You've really helped me out a lot in my first year of tumbling. Thanks for all the help you've been in your videos and on the forum.

[@MichiganRocks]

I'm glad you find the videos helpful, Sam. Until you start tumbling, I think it's hard to understand that some rocks polish up great and others don't. Hopefully this helped clear that up.

[@t2gunner]

@@MichiganRocks I've heard the advice, but the visual drives it to understanding... #RockOn

[@kokosnood]

I based my whole tumbling method on Rob's videos. THANKS ROB!

[@paigey-poo4235]

Fir me the allure of tumbling has never been about making the rocks look “perfect” but to just see the potential of the rock’s character, to see what unique qualities you can bring out of a piece! And a lot of the rocks here are perfect examples! Sure, everybody and their brother has shiny rocks, but finding and working something into a one of a kind palmful of art? That’s my goal! There’s certain qualities of the rock you can’t see unless you break it, tumble it, etc!

[@MichiganRocks]

I enjoy the process of tumbling more than the finished product. But for me, the challenge is to make them look as perfect as I can. I realize that not everyone has the same goal as I do. The problem is that I tend to show only those perfect examples on my channel. I thought people should know that not all rocks turn out perfect.

[@blackcat14077]

Sums up my thoughts perfectly!

[@Rocking-SLC]

Hey Rob, what a great demonstration showing some rocks are just not tumble-worthy. Some are perfect just they way they are such as the brachiopods. Others just turn out really disappointing in the end. Thanks for helping your viewers avoid tumbling pitfalls and have a happy and prosperous new year.

[@MichiganRocks]

Happy New Year, Earl. I think you have to tumble a few bad rocks yourself to really get the feel for which ones to pick up, but hopefully this speeds up the learning process a little.

[@nikkilovesrocks]

I'm stuck in a condo in Southern CA & I'm loving these vids! I have a 5lb bucket with my collection of raw crystal rocks which I would love to tumble. I hope my year ends more like your year begun! 💖✨

[@desertflamingos]

Even though I have been picking rocks up my entire life, I am brand new to the tumbling world. I have seen so many of the “perfect tumble” videos it is hard to picture a bad tumble. This was very educational. Thank you!

[@MichiganRocks]

Good, I’m glad my failure has been helpful.

[@gwynnfarrell1856]

Sometimes a rockhound has just got to see what happens in the tumbler. You never know what might become an unexpected gem! Thank you for showing each rock as it progressed. I like that you included the Christmas ornaments as controls. Very educational! Happy New Year! 🎉

[@MichiganRocks]

I'm hoping this helps a few people. I get a lot of questions about what rocks should be picked up on the beach.

[@R.M.MacFru]

Well, I have just learned I'm not as much of a magpie as I thought. 😆 While the batch is not as shiny as your usual, I still think the tumbling was worth it for the color and patterns, particularly the one with the crystal pockets. (This is probably why I love geodes so much.) I was happily shocked that the specular hematite stayed intact. I was expecting glittery slurry. And on the one with the big hole...I like the contrast that tumbling created. The hole is the most interesting part of that rock, and the contrast makes it pop out, so to speak.

[@MichiganRocks]

I generally don't like holes of any kind, but I do like a large hole if it's full of crystals. I have seen some spheres that have half the rock missing completely that look really cool. I also like crystal hole in a cab sometimes.

[@sparband]

I think that my favorite was the sparkly hematite. I liked the stink stone because it was different. They came out better than I thought too. I love the colors of the granite. It’s too bad that it undercuts.

[@MichiganRocks]

I think granite is probably the most collected rock by beginner rock hunters. There's nothing wrong with that. I did the same thing. But after tumbling a few batches of it, I stopped picking it up.

[@thomasnaas2813]

Love your casual, experimental approach. I've run into rocks that don't tumble well, I sometimes use a dremel with buffing wheels and diamond grit to good effect. For the porous stones I mix stone powder of similar hardness with slow drying epoxy, submerge the rocks and stick them in a vacuum pump container for thirty minutes and remove them before it hardens. Tumble on!

[@MichiganRocks]

I've never tried stabilizing rocks with epoxy (or anything else). I do realize that some of these could be worked on a cab machine or some other sort of grinder with better results. There's more than one way to polish a rock!

[@salishseaquest7952]

Rob, this was actually very informative. I appreciate all the time you devoted to getting us through the process on all the underrated rocks. It's many weeks of tumbling. I think for the most part you were right because you know what you like -- beauty is definitely in the eye of the beholder and the one who is running the tumblers. Happy New Year to you and Nancy!

[@MichiganRocks]

Happy New Year!

[@johnsopko24]

I live in Michigan. I found a dirt road that the city laid gravel on and it's loaded with every color quarts Greenstone and about every gem Michigan has. I also have found alot of emeralds in gravel around here. I love rock collecting in Michigan.

I'm new to tumbling and I count on you and your methods to receive a "good education". I think you're a natural teacher, I've learned, tumbled and practiced my happy dance. Thank you (a million times) for your efforts.

[@MichiganRocks]

Wow, I'm glad you've found my videos so helpful! Thanks for the nice comment!

[@adamschaafsma5839]

I'm so glad you did this, it makes me feel like it's harder to mess up, and I feel more encouraged to just dive in and tumble.

[@MichiganRocks]

It's hard to mess up tumbling too bad. Even if you have a batch that doesn't turn out like you'd like, you can always run them over again. Think of any mistakes you make along the way as learning experiences. I've learned a lot in the past ten years or so.

[@katherinehanna3968]

Loved seeing the before During and after tumbling. I haved collected some smaller pieces that I want to use as wearables, pendants and dangling accessories including earrings, belts, and ties or lacing, many of these are small peanuts or jelly bean sizes in colors from icy white, cool blues/grays, and warm orange/ peachy colors, flattering against skin

[@MichiganRocks]

Sounds like you're going to make some nice stuff!

[@leannesutter9429]

Thank you, Rob for taking the time to demonstrate this. It gave me a better understanding and will help me to make the decisions with how I clean and polish my Great Lakes finds. I appreciate your explanations on why you prefer polishing certain rocks, how you grade the finished rock/fossil at each stage of the process and the challenges you had with some of them.

[@MichiganRocks]

I get questions fairly often about what rocks should be picked up. The short answer is that you should pick up whatever looks good to you. But that answer doesn't help too much if you're planning to tumble them. I'm glad you found this useful, that's what I was going for.

[@clwbchbabycakes]

That first fossil - I would have oiled that like I do seashells. It brings out the color without damaging the piece since those don't need to be shiny. Things that look good wet but not dry - like Petosky stones - can be oiled. The holes with the druzy crystal are awesome!!

[@MichiganRocks]

Yes, I have some rough Lake Superior agates that I keep oiled. I don't oil my Petokseys though, I like those just polished.

[@KristiStClair64]

What kind of oil do you use? They don't go rancid?

The sandstone may not polish but big pieces look great in an aquarium. Cherry shrimp love picking microfauna off the rough surface. It was interesting to see how they tumbled.

[@MichiganRocks]

That one came out of the tumbler pretty much how it went it, but smaller. I agree that some rocks can look great even if they don't tumble well.

[@WagonPilotAdventures]

Great video for beginning tumblers to show how different rocks turn out. I think a lot of people start with very high expectations due to rock tumbler advertising pictures. I still tumble a lot of granite since it's plentiful near my house, which makes it easy to experiment and fine tune my methods. Keep up the good work!

[@MichiganRocks]

Have you figured out a way to stop the undercutting?

[@WagonPilotAdventures]

​@@MichiganRocks Not yet. Granite patterns are so random. I'm just getting back into tumbling after several months off, but I do have two 1lb Nat Geo tumblers now. Going to run some days/grit tests as soon as I finish some pudding stones. Starting to film too.

[@txwaterbird6115]

Just catching up on rock tumbling videos and your stink stone caught my eye. I actually like it. Those holes give it an interesting look. If I were tumbling it, I would use my water pic to blast out those holes. That's much quicker than a sewing needle. This process only works because my husband and I each have our own water pic. He would not appreciate it if I used a shared tooth implement on rocks.

[@MichiganRocks]

I lot of people have suggested both Waterpiks and ultrasonic cleaners. I might need to get one or the other.

[@denisemurray412]

I got a beginner tumbler last year and I’m really excited to go down to the river and see what rocks I can find once the weather warms up. I don’t think I’ll be so picky but this video gave me a lot to think about when choosing rocks.

[@MichiganRocks]

You don't have to be so picky. I didn't start out that way. The thing is, I show a lot of rocks that are much more perfect than these. I thought I should show examples of rocks that don't turn out the same as what I usually show here.

[@MichiganRocks]

That's a super pretty rock. Too bad it's so soft.

[@oldhaggys]

I love stones with contrasts on them. Different textures, different colors, different angles and so on. Therefore i love the granit, the stinkstone, the omar. Also I would probably love the granits if they are bigger so I can use them for sensory / fidget stones. The undercutting gives that contrast when you fidget with them

[@MichiganRocks]

It's not that I don't like these rocks. It's that they don't polish the same as the beach rocks that I usually show here. I wanted to do a video showing that not every rock on the beach will tumble the same way.

No, the polish stage is what usually damages Petoskeys more than any other stage (except maybe the 500 stage). It's really hard to tumble Petoskey stones.

hey rob, so i’m a beginner for tumbling completely, i’m gonna order one of the national geographic tumblers the hobby edition one, as you said in your review the polish is really bad, so i figured i’d get that separately. i found one that looks okay and i wanted your take on it, for step one it’s silicon carbide F80, step two is silicon carbide F220, step 3 is silicon carbide F400, and finally instead of aluminium oxide is ‘pumice powder’, i remember you saying that aluminium oxide is really good for step 3 and 4 so should i go for a different one?

[@MichiganRocks]

I have never heard of using pumice powder for a polish. I also strongly recommend that you use aluminum oxide as your prepolish. I have a link to the Rock Shed in the description. That’s where I buy my stuff. i also buy from Kingsley North for coarse grit. That link is also in the description.

[@txwaterbird6115]

My bete noir is ruby in zoisite. I know there's a way to tumble it and get a shine. My brother-in-law who is a geologist collects spheres and has a beautiful shiny one. The problem for me is that I keep trying to polish it (ruby in zoisite) over and over again. So if you have any ideas, I hope someone out there might have a hint or 2. 🙏 Thanks for the video. As always, yours are fun and informative.

[@MichiganRocks]

I have only seen pictures of that, never tumbled it myself. I just looked up the two minerals and found that zoisite is 6-7 and ruby is 9 on the Mohs scale. I think that's your problem. Silicon carbide and aluminum oxide are both 9 also, so they're going to have a hard time with the ruby, but will easily wear the zoisite. That's going to cause undercutting, or uneven wear on the two different minerals. Your brother in law's sphere was not tumbled. It was probably ground with diamond grinding cups. Some rocks will turn out much better on a cabbing machine or some sort of grinder than they will in a tumbler.

[@tonys.5940]

So based on the results, are you more likely to try tumbling questionable rocks or stick with your previous hunches?

I don't think Harbor Freight sells a vibratory tumbler for rocks. I'm pretty sure they're all designed for metal and dry media. If so, the barrels and/or motors won't hold up to the weight of rocks.

[@berjo77]

@@MichiganRocks Yes, after I mentioned it, I read more, they don’t easily perform well, some leak and seldom hold up. I’ll keep looking and studying. Wait till I can pick up a real rock unit.

[@jordanstevens3]

I liked the explanations you gave along with what your expectations where

[@MichiganRocks]

Thanks. I'm not always right, but at least you know what's going on in my head.

Great video I'm learning a lot!!!!! Happy new year! Thanks for the videos!!!!!

Happy New Year!

[@kimfrommn7162]

Very interesting!! I'm starting to catch on!! It was neat to see how they turned out!! I like the rocks real shiny and perfect like you do. But all the rocks that were just tumbled, I liked them also!!! Thanks for taking out the time to show us!! Happy Happy New Year!! May the two of you have only good things coming your way!! 🤗❤️❤️🙏🏼🎄

[@MichiganRocks]

Some of this stuff is best learned by actually trying things yourself. I think making your own mistakes is one of the best ways to learn. Hopefully this helps out just a little. Happy New Year, Kim!

[@lynschultz513]

Good lesson on tumbling and what rocks to choose to get the best results.

[@wyomingadventures]

I appreciate your educational tumbling videos! Thanks Rob.

[@tigerg3761]

Really like the way the Omar turned out. Love the contrast. Hope your 2022 is off to a great start!

[@MichiganRocks]

So far 2020 is awesome. I'm working on a video that I'm really excited about.

[@ripadipaflipa4672]

I grew up on Lake Superior and enjoy Ur channel partly to reminiscing over the rocks I can’t find in FL 😂 I really like it when U say the rocks point of origin and type of rocks Ur using plz keep it up Thank!

[@lucisue53]

I'm a first-time viewer of your channel and wanted to thank you for the detailed information about your process. I am a geologist by training, though it has been many years since I worked in that profession. May I share a tip for cleaning grit out of the pits and holes that you had in some of the rocks? A dedicated WaterPik will help blast into the holes to loosen and remove the grit efficiently. That particular brand (maybe other brands too) can be fitted with different nozzles that focus the spray for different spray intensities, and the flow volume can adjust as well. Thanks again for the informative video - so much fun to watch. It brings back great memories of the rock tumbler we had in school.

[@MichiganRocks]

It's kind of funny how many people have suggested that recently. Probably a couple a day for the past week. I participate in an online lapidary forum where some people have suggested a fabric spot cleaning gun. It sounds like they have more pressure than a Waterpik. I think I'll have to try one or the other. Thanks for the tip.

[@SherryAustinMcginley]

What a good video! We all draw our line in the sand at different places so what’s good for some won’t be good for others. I tend to agree with you and like the smoother, shiny rocks the best.

[@MichiganRocks]

Welcome to team smooth and shiny!

[@easterazali9237]

You were absolutely right master there is a huge difference between hard rocks and soft ones ! You know your rocks for sure ! 🥰👍 Happy new year to you and the family ! 🥳🎉

You're welcome, Greg.

[@Star_Rattler]

Thoroughly enjoyed watching and listening to you explain. I love learning about interests of mine and I've always loved collecting cool rocks ever since I was little. Thanks for putting the time in to make this video. I'll watch some of your others as well, and I subbed. I always love people who pursue their passions and hobbies like this, it's really inspiring. I want to go to the beach now but Long Island Sound doesn't have the best samples.

[@MichiganRocks]

Michigan isn't great for rock hunting this time of the year either. The water is better when it's liquid.

[@Star_Rattler]

Thanks for this demo, Rob. This gem of a video is bound to save a lot of us from making the same mistakes. You were pretty much spot on with what you initially thought or knew. Surprise, surprise Lol. Wishing You and Yours a prosperous New Year ahead and the most Spectacular rock and or whatever desirable finds available to you. The same to Everyone else too. Love and Blessings from Nor Cali.

[@MichiganRocks]

Thanks! I hope I speed up the process, but everyone has to tumble some of their own local duds to get a feel for what works and what doesn't.
