A Petoskey stone is a rock and a fossil, often pebble-shaped, that is composed of a fossilized rugose coral, Hexagonaria percarinata. [1] 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 (and some in the northeastern) portion of Michigan's lower peninsula.

The darker blue color resulted in limestone from this region being dubbed "bluestone" and with two sequences measuring about 10,000 feet (3,000 m) thick, it gives the area one of the largest limestone deposits in the world. [20] The stone eventually fades from a deep blue to a light grey after prolonged exposure to sun and rain.
