Will This Huge Petoskey Stone Polish?

Today I'm polishing a 12.5 pound Petoskey Stone. It's always a little hard to tell if one this rough will turn out or not, but you'll just have to watch the video to find out. I used the following polishing pad grits: 30, 50, 100, 200, 400, 800, 1500, 3000.

Darn right I will be happy with it!

[@ChrisRocks-ki8fr]

Thanks again Rob! I don't think I would have the patience to spend 6 hours working on that. Great job and I am not surprised that a lot of people like the bottom.

[@MichiganRocks]

I’ll get it in the mail for you one of these days. Glad you like it. Thanks for letting me play with it. Luckily it was a beautiful day to spend outside.

[@vickilynn1204]

My favorite part of the rock was the bottom. Beautiful

[@MichiganRocks]

Me too.

[@jerrywiessner]

Great video Rob. Been watching for a few years now. In 1967 when I was 12 My dad and I found a huge Petoskey stone in some woods near Petoskey. We couldn't carry it, so unfortunately we took a hammer to it. My dad made lots of lower Michigan shaped pendants and broaches out of it. He always wanted to make an upper and lower one, but they were to fragile. Of coarse I helped him with some sanding, but mostly polishing on corduroy with aluminum oxide. Lots of memories.

[@MichiganRocks]

I have made some Michigan shaped fridge magnets, but not pendants. Sometimes I make the U.P. sometimes I don't.

[@ccccarriemchardy9216]

He will be stoked, it looks fantastic!.

[@virginiarocks]

Wow! I would imagine Chris will be very happy. That is lovely! Well done. Thanks for sharing, Rob!❤

[@jeffholmes1362]

Nice job Rob, I love the bottom , but a sample that large is bound to have issue spots. Well worth the time, thanks for sharing

[@MichiganRocks]

Overall, it was really nice, even with a few blemishes.

[@markhorn9239]

Holy Petoskey, Batman! Nice job!

[@kirar2180]

Lol, I might need to add this phase to my vocabulary

[@MichiganRocks]

Ka-Pow!

[@sboydrocks9412]

What a huge task. No doubt you would love to be 12 foot tall and work on a cabbing machine twice the size you have and hold the stone in your 12 foot high giants’ fingers. I think it came out awesome and considering the size of stone and the tools involved- have gained an huge respect for the skills of sculptors and stone masons and the tools they have to use. Thanks for sharing Rob.

[@MichiganRocks]

That would have been a whole lot easier!

[@wyomingadventures]

Nice job Rob. I'm sure Chris is going to like it. I like your idea of making a vise to hold the rock while you work on it.

[@MichiganRocks]

My "vise" works sort of well, but it's not perfect.

[@EricTheCat]

That turned out really nice. Great work!

[@lynettepavelich7540]

One of the nicest rock bottoms I’ve ever seen! That size of petoskey would make my day!❤️

[@sunnycadwallader2873]

So interesting to watch the progression in polishing. Thanks for a great video.

Hi Rob, a great job, love that stone

[@Mgrucza55]

Hello from Erie pa ...our beach walnut creek and trout run is fun I love white stones but I love watching g you and your wife ❤

[@DurpVonFronz]

Daaaang, that turned out awesome Rob!! The bottom was unreal kewl looking, so didnt think it was going to look like that at all :)

[@MichiganRocks]

That's what the bottom of a Petoskey stone looks like, but I don't usually get to polish any as big as this one. Bigger is better in this case.

[@JimFry]

Fantastic start to final. These are always a challenge and why I procure so many replacement wheels for my Genie.

[@MichiganRocks]

This was a little big for a Genie, but I wish I could have done it that way.

[@marybeth6272]

That one is a beaut. ❤❤❤ You should have shown his reaction to you giving it back. Love the video.

[@MichiganRocks]

That would have been fun, but I needed a video for this week and I didn't have time to send it out to get Chris's reaction in time.

[@deadiemeyers1661]

I have become quite smitten with Petoskey Stone. Loved seeing this brought to such a beautiful condition.

[@MichiganRocks]

They're pretty common around here, but I still get excited when I find a really good one.

[@kittyfruitloop8264]

I love Petoskey stones! I was born in charlevoix. Your accent makes me homesick. I live in GA now.

[@MichiganRocks]

Charlevoix is a nice town too. When I was in high school, my parents owned a 22' Sea Ray with a cuddy cabin. We would take little three day trips in the boat and stayed in Charlevoix more than once. One time we were there when there was a concert at the Castle. My parents let us walk from the harbor to the castle to attend the concert. I can't believe we got away with that.

[@Algorhythmz]

Beautiful!

[@manisteerocks7092]

very nice job!

[@nancymcshane3501]

Surprised at the pattern on the bottom! Great job! Went to one of the big Gem Shows in Franklin, NC today. Saw lots of rubies!

[@MichiganRocks]

Rubies are fun.

[@donnalantz7981]

Well now I know I need to get both kinds of grinders. LOL I have a few really big rocks I would love to see if I can polish someday. 1 is quartz and I'm not sure what else. It's really big but I love everything about it. I love learning from your videos. Thank you so much. That Petoskey turned out super I think.

[@MichiganRocks]

I have done more puddingstones than anything with that grinder. It works pretty well.

[@easterazali9237]

It looks really beautiful Rob how kind of you to spend 6 hours polishing it for your friend , God bless you 💖

[@MichiganRocks]

He got a rock and I got a video. I spent about the same time making this video as I usually do if you count the time on the beach as part of the video. He was nice enough to offer me something to do for a video that I don't normally get a chance to do. Everyone wins!

[@CHBT2021]

Such a pretty rock afterwords. I don’t think I could do such a favor for a friend without pranking them first. If I were you I’d meet up with the owner and hand them a similar rock but palm sized and say “there ya go buddy… it took me two days but I shined it up nice for ya” haha.

[@MichiganRocks]

I have a brother in law who once replaced the turkey in his mother's oven on Thanksgiving day with a Cornish hen. He says she was really surprised when she opened the oven to check on it.

[@johnrau6568]

Have you ever put a large Petoskey stone in a form and covered in epoxy? Wondering how that would look. Great video Rob

[@MichiganRocks]

Nope, I have only used epoxy resin one time, and that was to make a top for a desk I made for my son. I made the whole desk, including the top out of cedar, which is way too soft to make a good writing surface.

[@soul_adventurist]

Nice!❤

[@EmHeg]

Hi there! Really appreciate your videos - was just gifted a tumbler for Mother's Day and I'm preparing to start my first couple batches. Today, I found what I think is a bunch of Serpentine which seems to be about a 5 or 6 hardness.. I know it's softer than suggested for newbies but I was advised that as long as I tumbled just the Serpentine together and keep my expectations low, it might actually turn out nicely 😆 Would appreciate any tips for better success, thank you!

[@MichiganRocks]

Worst that could happen is that you waste a little time and learn something. I have learned a lot by just trying things.

[@jeffreydemeter3819]

Helpful video! Was wondering about best way to polish large petoskey rocks. Have a question on polish. Do you have experience using Zam when finishing a petoskey stone?

[@MichiganRocks]

Yes. Zam works well on them. I don't have a large buffing wheel to use it with big rocks though. I usually use it with a little felt wheel on my Dremel.

[@darkwood777]

Spending the whole day on your feet grinding away at that rock gives a man a chance to think.

I was listening to podcasts about geology, so I was thinking about geology.

[@salishseaquest7952]

Rob, did you weigh it post-polishing? Just wondering how much stone you removed..... Finished polished rock was amazing!

[@girlonaswing9439]

That was fantastic!!! I probably have the smallest Petosky stone.🫣

[@MichiganRocks]

Yep, I was going to mention that, then completely forgot to. It lost four pounds, about a third of its weight.

[@salishseaquest7952]

@@MichiganRocks WOW! That is amazing to remove that much and you were able to maintain the integrity of the stone and its beauty. Well done! But then you are the expert when it comes to the Petoskey Stone -- lots of practice over the years.

[@amitamodzelewski3425]

My family is heading to the east side if the state for a week, I was wondering if you could recommend any beaches for rockhounding. We are going to stat camping near the Ausable River primitive camping, then going north along lake Huron. Any suggestions we love to add a couple of rocks from each trip to our rock garden.

[@MichiganRocks]

Sure. Harrisville State Park (smallish rocks) Sturgeon Point Lighthouse Negwegon State Park (walk north about .75 miles to get to the rocks) Partridge Point Park just south of Alpena Rockport (great spot for fossils on the beach, in the old quarry. Also sinkholes behind quarry) 40 Mile Point Lighthouse

[@JimFry]

Rob, it was great to stumble into you at Swede's today. What are the chances?

[@MichiganRocks]

Oh, now I recognize your avatar. I talk to so many people here that I've never met in person, it's hard to keep everyone straight. It was nice to see one in person for a change. Sam and I had a really good day out and found lots of rocks, mostly tiny agates and carnelians. I found one of the best agates of my life. It was mostly green, really green. You'll see it in a video one of these days.

[@maryseaman312]

Does the pattern go all the way from the bottom to the top? You have just finished the 400 grit, and it sure looks like you could go all the way through. Have you ever sliced one of these up into slabs?

[@MichiganRocks]

Yes, the pattern goes all the way through. It's fossilized coral, so the coral grew from the bottom to the top and it's all preserved. I have sliced many of these into slabs, but never one this big.

Please forgive my ignorance but, what is a Petoskey stone?

It's a fossilized coral. It's also the state stone of Michigan.

Its strange i have found a so called Petoskey stone here in Hungary on the coast of the Danube.

Do you think it would have been shinier if you had used your cab machine for the final touches? Did Chris ever say which side of the state he found it (Petoskey side or Alpena side)?

[@ChrisRocks-ki8fr]

It was found in the Petoskey area. That is as far as I am willing to go. 😁

[@MichiganRocks]

Yes, I can get them shinier on my cab machine. This rock was just way too big to use the cab machine though.
