Geodes are a beautiful, natural phenomenon. They are hollow rocks with a mass of crystals inside and are formed when a cavity is created in a rock. Then crystals form in the crevices from water flowing through. 

Because of their intrigue and unique appearance, you may want to know how much geodes are worth and what the most expensive geode in the world is. 

There are a range of factors that influence the worth of a geode, and they can be sold from as little as $5 to more than $1000. These factors are:

  • Crystal in geode
  • How the geode is cut
  • Weight and size
  • Symmetry 

The crystals that are found in a rock influence how much geodes are worth. Many geodes contain Clear Quartz, making the rock common and worthless than others. Some geodes contain rarer stones, like Jasper and Agate. Many of the more expensive geodes are made from Amethyst crystals. 

Another huge factor that determines the worth of the geode is how the rock is cut and opened. When cut open correctly, the geode will display the crystals and not have any other splits or cracks in the stone. The symmetry found in the geode affects the price. A more symmetrical geode will fetch a higher price. 

The weight and size of the geode also affect how expensive they are. A larger geode is worth more than a smaller one.
