Designated the state stone of Michigan in 1965, Petoskey stones Hexagonaria percarinata are coral reef fragments deposited during the Devonian period, and later carried by glacial movement.

Petoskey stones can be found on various beaches and inland locations in Michigan, with many of the most popular being those surrounding Petoskey and Charlevoix. The movement of the frozen lake ice acting on the shore during the winters is thought to turn over stones at the shore of Lake Michigan, exposing new Petoskey stones at the water's edge each spring.
