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. This is a "grab bag" item. That means we will pick one from our available inventory and send it to you. Pictures of the actual material is shown. No two specimens are alike.

It's a polished Petoskey stone. What's not to like? It is a stone and it's polished like advertised. I ordered it for my wife's birthday, she's from Michigan. The sellar said he would try to get it there on time, as I ordered close. He was awesome and pulled it off.

...but it was only polished on one side so I did return it with no problem. Very nice people to deal with.
