Geodes are hollow, unassuming, rounded rocks that contain hidden, sparkling crystals—such as quartz, amethyst, or calcite—formed inside over millions of years. They develop from gas bubbles in volcanic rock or cavities in sedimentary rock, where mineral-rich water seeps in and crystallizes. Geodes are often found in volcanic or limestone areas, frequently in gray, rough, and light-weighted rocks.
