About

In December 1999, members of the Madrid Mineralogist Group discovered the Pulpí Geode in La Mina Rica. The geode is about 8 metres long by 2 metres high covered with huge gypsum crystals. The Pulpí Geode is lined with gypsum crystals, which reach up to 2 metres in length. The transparency and perfection of the crystals make it a jewel of nature. It is a unique phenomenon worldwide given its dimensions and perfection, and the size and transparency of the crystals (Calaforra and García-Guinea, 2000).
