A geode is a term of mineral collectors, meaning a bubble in the rock which is filled with minerals. Because of the hole in the rock, water seeping through the pores of the rock transports minerals to the hole and in the mineral rich water crystals start to grow. Generally geodes with a few centimeters in diameters are sold, items with half an meter are really expensive. But sometimes a geode with a size of several meters is discovered, and actually any natural hole in the rock which is big enough to be entered by a human is a cave, thats the definition of the term.
At the Mina Rica the geologist Javier Garcia-Guinea discovered a natural geode which is 8 m long and about 1.8 m in diameter. It contains selenite (gypsum) crystals which look like blades of glass, transparent and up to 2 m long. In average they are 50 cm long. He named it Geoda Gigante.
The geode is a unique natural wonder and it is protected by law, on the other hand there is the urge to develop it for tourism, make it accessible for tourists. This is both an economic and an educational topic. Unfortunately the crystals are very delicate, easily shattered, and destroyed even by minimal changes in humidity and carbon dioxide content of the air. So originally the development for tourism was not possible and there was a plan to create a replica. At the end the geode was developed and is now open for tourism. The operators state that temperature, humidity and Co2 in the air are monitored accurately and the number of visitor is limited so it will not destroy the crytsals, but this is obvioulsy
