Geodes are rock cavities with internal crystal formations, usually made of quartz crystals. Some geodes are completely solid because they are filled with crystals. These are called "nodules". Geodes can form in gas bubbles in igneous rock, or in rounded cavities in sedimentary rock. Most geodes contain clear or white quartz crystals, but purple amethyst crystals are also common.

How can you tell if a geode is real?
The only way for the average person to tell if a rock is a geode is to crack or saw it open and have a peek inside.
