Lake Superior Fossil Coral, Collectors Stone, Polished

I find these Lake Superior fossils on along the south shore of Lake Superior. This one is unique in that it's lightly agatized. These fossils are uncommon to find. The agatized pieces are much more rare to find. I polished the end of this stone while leaving a small geode area that sparkles as the stone is moved.  The other areas are left as it was when we pulled it from Lake Superior. This stone measures about 1.25 x .85 in inches.
