Collection: Petoskey Stone

Petoskey Stone is a rock and a fossil, composed of a fossilized rugose coral, Hexagonaria percarinata. Such stones were formed as a result of glaciation, in which sheets of ice plucked stones from the bedrock, grinding off their rough edges and depositing them in the northwestern portion of Michigan's lower peninsula. In those same areas of Michigan, complete fossilized coral colony heads can be found in the source rocks for the Petoskey stones.

Petoskey stones are found in the Gravel Point Formation of the Traverse Group. They are fragments of a coral reef that was originally deposited during the Devonian period. When dry, the stone resembles ordinary limestone but when wet or polished using lapidary techniques, the distinctive mottled pattern of the six-sided coral fossils emerges.

In 1965, it was named the state stone of Michigan.

Petoskey Stone helps us recognize and acknowledge our emotions, a very important step in learning to love ourselves. It works on both the Third Eye and Crown Chakras. It helps us develop our intuitive abilities. This is a good stone to help anyone with their creative side to bring abundance to projects.
