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.
