Most geodes have a white interior however its also possible to find geodes having light pink purple or blue colors on the inside. Where Can You Find Geodes. Geodes can be found anywhere in the world and are most commonly located in deserts volcanic ash beds or regions containing limestone.

Minerals seep into the holes and harden. Geodes in sedimentary rocks are usually found in limestones dolomites and calcareous shaleIn these deposits a gas-filled void can serve as the opening for geode formation. Most of the time the outside of the geode will have a brown or grey color.

Check if the geode is completely filled on the inside or if it is has an open space with crystals.

Check in limestone areas that have signs of visible drainage. Dont spend time here as it has been picked over. Since geodes are hollow with crystals it should sound and feel hollow when you tap it on the ground.

It is best to have a map of good locations to find geodes.
