Petoskey stone

The Petoskey Stone is a polishable as gem stone, rock composed of fossilized coral skeletons that were growing in a warm sea in Devon, and Lake Michigan ( Great Lakes ) in the U.S. state of Michigan is found. First colored greyish - brown, the honeycomb-shaped pattern, which is generated by the cross-sections of the housings of the individual polyps coral appears after wetting. The scientific name of the coral Hexagonaria percarinata was derived from the hexagonal shape of the coral sections.

The name is from the village of Petoskey (Michigan ) and thus derived from the Ottawa chief Petosegay, whose tribe formerly lived in the area of the place where these stones are most frequently found. Governor George W. Romney told the Petoskey Stone on June 28, 1965 the official state stone of Michigan.
