Uncovering the Differences Between Petoskey and Charlevoix Stones

Michigan is famous for its beautiful shorelines, some of which are dotted with unique stones. The western shorelines of Michigan are home to two types of stones that rockhounds eagerly seek out.

These are the Petoskey stone and the Charlevoix stone. While both may appear similar at first glance, upon closer examination, they exhibit certain distinct characteristics.

In this article, we will delve into the differences between these two stones as well as how to find them and add them to your collection. Types of Stones Found Along Michigan’s Western Shorelines

The first step in understanding what makes these stones so special is to take a closer look at their physical attributes.

Both the Petoskey stone and Charlevoix stone are fossilized coral specimens that are hundreds of millions of years old. They are remnants of an era long gone, a time when the world looked very different and the ocean teemed with life.

Petoskey stones are characterized by their hexagonal corallite pattern, which is an intricate design of small openings that create the honeycomb pattern on the surface of the stone. These stones are primarily made up of fossilized coral specimens from the Tabulata group and the Rugosa group.

Charlevoix stones, on the other hand, have radiating lines and coral tubes that create a distinct pattern on their surface. They are primarily made up of fossilized coral specimens from the Favosite group.

One notable difference between the two stones is their origins. Petoskey stones are named after a city called Petoskey and are found primarily in the northern part of Michigan.

Meanwhile, Charlevoix stones are named after the city of Charlevoix and are found in the southern part of the state. Another difference between the two stones is their age.

Petoskey stones are thought to be around 350 million years old, while Charlevoix stones are around 400 million years old. This is because Charlevoix stones are typically found in deeper rock formations that are older than the rock formations where Petoskey stones are found.

Finding Charlevoix and Petoskey Stones

Now that we have a better understanding of what these stones are and the differences between them, let’s talk about how to find them. There are a few things to keep in mind when searching for these stones.

Lake Ice and Shoreline Exposure

The best time to search for Petoskey and Charlevoix stones is during the winter months when the lake is frozen. This makes it easier to access the lake bed, and the stones are more exposed.

Storms and high winds can also stir up the lake, exposing stones on the shoreline.

Locating the Stones

Once you’ve identified a location to search, start combing the rocky beaches. It takes patience to find good specimens, but once you have a collection started, polishing your finds can bring out the beautiful pattern and color variations in the stones.

If you’re looking for a quicker way to add these stones to your collection, check out local lakefront shops or look online for sellers.
