Take a Walk Inside the World’s Largest Geode
In 1999, the biggest geode in the world was found inside an abandoned silver mine in Spain’s Almeria Province. It was closed in 1969, this cave is now rich for geologists because it contains the Pulpi Geode, a giant rock cavity packed with shimmering crystals. While not everything is known about how geodes are created, these structures contain a wide mixture of minerals.
The Pulpi Geode is 8 meters wide, 2 meters long, and 2 meters deep, making it the biggest on earth. Since opening to the public in 2019, more than 100,000 visitors have come to Pulpi to look at the wonders of nature and the silver mine’s history.
The Pulpi Geode continues to offer new discoveries as scientists search for when and how this richest of rocks came to be.
