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.
