What Are Geodes Anyway?
Geodes are fascinating geological formations with a hollow cavity inside (which is often lined with crystals or other minerals). They can come in all shapes and sizes, ranging from tiny pea-sized spheres to large, basketball-sized rocks. Geodes are formed when mineral-rich groundwater seeps into cavities in volcanic or sedimentary rocks and begins to deposit minerals.
We’ve prepared an in-depth guide on how to identify geodes so that you’ll have an idea of what to search for.
Over time, the minerals build up and create a shell around the cavity, forming a geode. When a geode is cracked open, it reveals a stunning display of crystals and minerals inside. The colors and patterns can be incredibly diverse, ranging from pastel pinks and purples to deep blues and greens. A geode’s value and appearance are substantially influenced by the kind of crystal inside it. Collectors highly seek after geodes and can be found in many locations worldwide. They are indeed a natural wonder that never fails to amaze!
