What are geodes? These seemingly ordinary rocks hide a sparkling secret inside. Geodes are hollow, spherical rocks lined with crystals or mineral matter. Found in volcanic ash beds, limestone, or even deserts, they form when mineral-rich water seeps into rock cavities and slowly deposits crystals. Geodes can contain a variety of minerals, including quartz, amethyst, and calcite. Their outer shell is often rough and unassuming, but cracking one open reveals a stunning interior. Collectors and geologists alike treasure these natural wonders for their beauty and the mystery of their formation. Ready to learn more? Here are 26 fascinating facts about geodes!
