Exceptionally large and hand polished HEXAGONARIA – “Petoskey Stone” Michigan’s State Stone. One can see the exceptional detail that makes this coral sought after. Though there are many similar corals found , none has the luster, shine and design of these beauties.

These are actually Devonian Corals from the area of Michigan that was once the bottom of an ancient Salt Water Tropical Sea over 360 Million years ago. Polished, these corals exhibit outstanding detail, right down to the septa within each corallite. Each corallite was an individual creature that made up these large colonies.

Often found on the lakeshores of the Great Lakes especially Michigan and Huron, these are exceptionally polished on all sides.

This stone is the one you will receive and is a partial side view of the corallites. It is approximately 2 inches long and 2  inches wide and 1 inch thick.
