Petoskey stones, a fossilized coral found mainly on the shores of Lake Michigan, are valued by rockhounds for their beauty and historical appeal. Not only do they make a prized addition to any rock collection, but they can also be used for jewelry and any number of crafts.
The stones are highly sought after, with their individual appeal depending largely upon size and quality. Polished stones generally draw greater interest than unpolished, although some stones are naturally polished enough by natural wave action that they require little more attention.
Are Petoskey Stones Worth Anything?
Petoskey stones do have value, especially those with the clearest features. Stones with a high shine can demand twice as much as dull, rough ones. The stones offer a fascinating view of the reef life of the past in startling detail for anyone interested in natural earth colors and design.
These unique stones have been turning up for sale all over. Even for those who do not collect fossils or gemstones, per se, the stone’s unusual pattern and history creates its own appeal. Petoskey stone jewelry and collectibles can be found in shops and online, where they seem to carry an ambiance all their own.
How to Estimate a Petoskey Stone’s Value
There are a number of factors that contribute to the value of a Petoskey stone. Unpolished stones are less valuable, especially if rough as found from an inland source. These stones are often priced by the pound, and the sizes may be smaller than average.
Smooth textured stones are preferable to most buyers, although some rockhounds may seek to include both a rough and polished stone in their collections. The clearer and shinier the finish, the greater value is placed on the stone. And even small stones increase their worth if set in a necklace or earrings.
Size is also considered when placing a price on individual Petoskey Stones. The average polished stone size found on online markets is around 1 1/2-2 inches. These stones may be sold alone or as a piece of jewelry or other collectible items. Larger stones, especially those with well-defined coral features, have increased value. Stones under 1 inch are considered small, 2-3 inches are medium, and over 3 inches are large.
Quality always plays a part in any fossil or gemstone value, and Petoskey stones can fit into either category. Stones without cracks or other defects are more desirable and therefore more valuable to buyers.
How Much Are Petoskey Stones Worth?
Unpolished, quality Petoskey stones are available at an average of around $4 per pound. This price is for about 2-5 stones per pound.
Some online sites charge up to $10 for a pound of raw, unpolished, small stones–up to seven stones to a pound. A 2-pound, 1/4 inch stone slab may cost over $30, and an ultra-polished, 8-ounce stone may cost up to $50.
Amazon offers Petoskey stones, polished and 1 3/4-2 1/4 inches, at a fairly decent price. (See below for current price)
Etsy advertises 5-6 inch stones for $55-$80. You’ll also find a variety of jewelry and collectibles at varying prices there.

Where to Buy and Sell Petoskey Stones
Petoskey stones are available at a number of rockhound sites online. There are also a number of Michigan sites that offer Petoskey Stone souvenirs from local sources.
As mentioned above, Amazon offers a variety of individual stones or stone products. Other online jewelry outlets offer various handmade creations. Pinterest can also connect you to sellers, as can Etsy.
If you are interested in selling your own Petoskey stone(s), Pinterest, Etsy, eBay, or even Facebook can help you get the word out about your products. By researching the sites, you can get a good idea about competitive pricing.
Again, the more highly polished and detailed your fossil is, the more you will be able to ask for it, so taking the time to polish rough stones can really be worth it. YouTube instructional videos or polishing kits are also available online to get you started.
