what state has the geode as its state rock
Geodes can be found in many places throughout the world. They often accumulate in stream bottoms. Some of the finest specimens come from the Keokuk area of southeastern Iowa, which has the geode as its official state rock. Many gem shops sell small geodes, which can be cracked open to find the crystals inside. Larger geodes are often cut, polished, and displayed. Reviewed by Donald L.
