Exceptionally polished HEXAGONARIA – “Petoskey Stone” Michigan’s State Stone.
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 coralite. Each coralite 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.
