Identifying Petoskey Stones From Other Fossil Corals

I thought I would stop the confusion about identifying Petoskey Stones from other Fossil Corals.  If can be quite confusing, especially if you do not know what the identifying differences are.  I personally love these gifts from nature!  They make unique and beautiful custom jewelry.

First off, Petoskey Stones are found on the northern shores of Michigan.  They are fragments of the Devonian Period coral reefs.  Petoskey Stones are fossilized coral (flower animals) that lived 350 million years ago.

The most unique feature of the Petoskey Stone is that they have a light or dark ‘eye’ in each cell of the coral.  These ‘eyes’ can be either small or large.  Other corals do not have these ‘eyes’.  Colors vary from light tan or gray to darker hues of brown.  Due to the fact that Petoskey Stones actually started out red in color, you might be able to find a stone with some red in it!
