|Florida's state stone! A high quality fossil coral specimen that features a large geode chamber filled with chalcedony "stalagmite" spires. Semi-translucent honey colored chalcedony appears to have seeded upon the threadlike columns of ancient coral itself in a process called silicification. The backside of this piece also shows nicely preserved detail of the original coral structure.
