Petoskey Stone
    This interesting stone is a variety of Calcite.  It was formed by the fossilization of ancient coral, Hexagonaria. The  coral lived in shallow waters and today's fossil often includes ancient  silt and mud. Petoskey Stones are found on many beaches of Lake Michigan  and Lake Huron, as well as in rock quarries from Travers City to  Alpena. The honeycomb patterned stone has a hardness from 4 to 5 and is  the official Michigan State Stone.
