Learn how to tell a quality Petoskey stone from an inferior Petoskey stone. Don’t waste time polishing Petoskey stones that are poor quality. I’ll show you examples of what to look for and what to avoid.
The Petoskey stone is the state stone of Michigan. It is an approximately 350 million year old fossil called hexagonaria from the Devonian period. It is made of limestone or calcite which is about 3 on the Mohs scale of mineral hardness. This makes it easy to polish by hand with sandpaper. Of course you can use lapidary equipment to polish them too.
I buy most of my lapidary supplies from The Rock Shed. I don’t make money from your purchases there, but I really think they have the best prices and the best service, so I feel good recommending them. https://rockshed.com
