Quartz geode

The quartz geode presented is a natural mineral formation where the hollow interior is lined with quartz crystals. These geodes typically form in volcanic or sedimentary rocks, where internal cavities are filled with saturated mineral solutions that crystallize over time. Quartz, composed mainly of silicon dioxide, is one of the most abundant minerals on Earth and often comes from regions such as Brazil, Uruguay, or Madagascar. Their formation can take several million years.
