I was over my brother in laws house and spotted this rock along the side of the house mixed in with landscape rocks and told him its looked like a petoskey stone. He had his kids start looking for more but they didn't find any. I thought about cutting it and making his daughter a pendant but I just face polished it real quick on the genie and plan to give back to his kids so they can keep it as a specimen. The diamond wheels make short work of these soft stones. no more than 5 minutes to do this. Chuck

That's a really nice one. Many of them have muddy eyes, but those are nice and clear with good contrast. Did you use some Zam on it? That really brings out the shine. I was in a Petoskey stone shop that only worked with Petoskey stones two weeks ago. The owner showed me her shop and the whole place was coated in a green dust from all the Zam she uses. She had big buffing wheels just for Zam.

I didnt get to the ZAM yet. My drill press that I use with a zam buffing wheel is in the garage which is about 35 degrees right now so I'll do that the next time it warms up a bit. Thanks for the reminder!

I use a Dremel with a little cotton wheel. I hit the wheel on the Zam and then rub it all over the stone. I haven't turned my basement green yet though.

Stayed at a Holiday Inn when i was a kid in Kentucky.The landscaped beds were full of limestone laced fossils-to this day some of the best i own.That will morph into a surprise to your inlaws.

Hey, how do you stop that green stuff from the Zam getting in the stone? Perplexed...

The stone isn't porous enough for it to get in there, I guess. My rocks have never turned the slightest bit green.

Really! I'm surprised because they look much the same. Hmm. Maybe my buff spins too hard or something...

I have had good luck with the ZAM on the few petoskeys I have done but I quit using it on my pudding stones due to the green getting in any tiny pits or hairline fractures. It shined them good but was not worth dealing with the green spots.

Well, I have now ZAM'd them all. It worked on some of them but others of them do have green crud stuck on somehow. It mostly happened at the beginning so...two questions. Can you overZAM a wheel? And how do you get the green off? Am trying a vinegar soak at the minute rather than backing up the Petosky stones completely since I already liked the shape.
At least I now have SOME polished Petoskeys which is a big step up from where I was stuck for...yikes...the last year almost.

I love the delicate design on the coral. Your polishing really brings it out!

My son and I have done quite a few Petoskey stones now and have never had a problem with Zam. We use a little cotton wheel on a Dremmel, so it.doesn't pick up too much Zam off the stick. Are you getting them smooth enough before the Zam? You're not tumbling them, are you? I use a coarse grinding stone first, then 220 and 600 SC, then a really worn out SC disk, then the Zam. I stopped in a Petoskey Stone shop in Petoskey a few weeks ago and the owner used almost the exact same process. She had large buffing wheels for the ZAm though.

I did tumble them and then just went to the Zam wheel. It worked for some of them...just not all. I guess I'll back up those others on the wheel when I get a bit more time. Yours came out beautiful, so it's an inspiration.

Tumbling Petoskey stones doesn't work. When you get to the finer grits or polish, it ruins them. I don't tumble mine at all.
