What Is a Geode Rock and 32 Types of Geodes

Geodes translate to Earth-like and are one of the few crystals that can purify and amplify energies. But what is a Geode rock? What is inside a Geode? What are the types of Geodes? What are the different Geode rock types?

Geode rocks are spherical, natural formations with a hollow cavity of crystals inside. Geode rocks usually look ordinary, but different Geode varieties cost up to $1,000 per carat. Healers say it represents rebirth, as it channels the energy of the thousand crystals inside it.

There are two main types of Geodes – Volcanic and Sedimentary – but there are dozens of Geodes. 

We will discuss all 30 types of Geodes with different minerals, their interior and exterior colors, features, benefits, properties, and locations. 

While there are Geodes with 25 different mineral compositions, they all come from two main types of rocks. 

• Volcanic: When lava cools, it leaves air pockets filled with minerals from the seeped-in groundwater. Ultimately, these minerals grow undisturbed for hundreds of thousands of years to become Geodes. 
• Sedimentary: When dirt fills up on the decaying bodies of animal remains, it creates air pockets and cavities of minerals. These minerals grow untouched for millions of years to turn into Geodes.

That doesn’t mean there are only two Geode varieties in the whole wide world. Today, we’ll learn about 30 Geode varieties (+1 bonus at the end) with their locations, uses sizes, and colors (interior and exterior).
