Naica cave, arguably the most magical cave of crystals, located in Chihuahua, Mexico, is the largest known crystal cave to grace our beautiful planet. This “Cave of Crystals,” also called the “Cueva de las Espadas,” was discovered in 2000 when mining for zinc, silver, and lead. 

Buried 984 feet below the earth’s surface, Selenite crystals forming over 36 feet and weighing up to 55 tons can be found. The Naica quarry is now closed, but you can still see exquisite pictures of the crystals found there.

The largest of all the mighty Selenite “wands” was reported at 37.4 feet (11.40 meters), a volume of 176 cubic feet, with a mass of 12 tons! Selenite is formed from gypsum, which is also known as calcium-sulfate.

Why is this cave closed? It was closed due to preserving this natural geological wonder.
