Deep below Naica’s mountain in Mexico, are amazing giant selenite crystals which has attracted world-wide researchers, both for its rare beauty and scientific mystery.
Cave of the Crystals or Giant Crystal Cave (Spanish: Cueva de los cristales) is a cave connected to the Naica Mine, with an amazing display of some of the world’s largest gypsum. These giant selenite crystals found in Mexico’s cave at a depth of 300 metres (980 ft), in Naica, Chihuahua, Mexico.
The Naica Mine, is a working mine and one of the world’s largest deposits of silver, zinc, and lead. Underground are the giant cavern with these large natural gypsum crystals: translucent gypsum beams measuring up to 36 ft. (11m) wide and 90 ft. (30m) long. Its walls studded with towering sword-like selenite (gypsum) crystals up to 2m long. The Cave of Swords is closer to the surface at a depth of nearly 400 ft. (120 m).
Despite its grandeur, the caves are closed to tourists due to dangerous conditions: near 100-percent humidity and temperatures as high as 136 degrees, warmed by a pool of magma sitting below the cave. Conditions are returning to their undisturbed state, allowing the crystals to continue to grow.
