History of Petoskey Stones

Petoskey stones are fossilized coral, unique to Michigan, and are known for their distinct hexagonal patterns. These stones date back to the Devonian period, around 350 million years ago, when Michigan was covered by a shallow sea. The coral, belonging to the species Hexagonaria percarinata, eventually fossilized and became embedded in limestone. Over time, glacial activity shaped and polished these stones, scattering them across Michigan's beaches and inland areas. Named after the Ottawa Chief Pet-O-Sega, the stones have become a beloved symbol of the state, cherished for their natural beauty and rich geological history.

Use in Artwork

Petoskey stones are rare and elusive, making the search for them feel like a thrilling treasure hunt. Their distinct hexagonal pattern, characteristic of fossilized coral, remains hidden beneath a rough, gray exterior unless the stone is submerged in water. Without the water’s reveal, they blend in with ordinary rocks. Once discovered, each stone embarks on a meticulous journey. It undergoes a week-long tumbling process through two stages, followed by careful hand sanding to smooth its surface. Afterward, the stone is hand-polished to bring out its natural beauty, ready to be transformed into a stunning work of art.
