The chamber contains giant selenite crystals (gypsum, CaSO4 · 2 H2O), some of the largest natural crystals ever found on Earth. It’s a unique place — let’s have a look at how these colossal ...

Unlike the giant crystal cave of Naica in Mexico, where mineralogists were able to study a still active crystal cave, the crystals in the geode of Pulpí stopped growing almost 60.000 years ago.

The crystals—a form of gypsum called selenite (CaSO 4 ∙2H 2 O)—took up to a million years to develop within a water-filled, magma-heated cave 300 m below the Earth’s surface.

Giant gypsum crystals up to 11 meters long in the Cave of Crystals, Naica, Chihuahua, Mexico.Gypsum is a naturally occurring mineral which is often used in industrial processes and which in nature ...
