Where are the largest natural crystals in the world?

The largest well -known natural crystals in the world are in the Crystal Cave of Giants, in the Naica Mine in Northern Mexico. The cave is full of selenium crystals up to 36 ft (11 m) and weighs up to 55 tons. These crystals are so impressive that when their pictures hit the Internet for the first time, the vast majority of observers called them fake. These natural crystals have reached their size for millions of years in almost perfect conditions, immersed in water rich in minerals with a consistent and optimal temperature of 136 degrees F (58 ° C). Earlier drilling emptied the lower reach of the water mine and the miners were looking for mineral bearings in unexplored areas of the mountain. What they found was unprecedented. The applied engineer, Roberto Gonzalez, immediately recognized the importance of the finding and ordered the tunnel to be redirected. The chamber had a temperature of 150 degrees F and had 100% humidity. Without protective equipment, the miners could only spend about eight minutes.

Unfortunately, in the first weeks after natural crystals were revealed, there was damage because the ruthless miners tried to take away some of them. One miner who slipped into the cave to stole crystals brought plastic bags full of air in an effort to extend the amount of time he could spend there; Unfortunately, this strategy (predictably) failed for him. Fainted and later found thoroughly baked. Soon thereafter, the mining company installed iron doors to protect amazing natural crystals. Unfortunately, Mexican law does not protect minerals from theft, which means that only a physical barrier can stop the thief.

mining company that disconc. At about 1000 ft (304 m) below the surface, the cave is Hluboká for a public visit and something would have to be done about high temperature. There is a concern that the reduction of temperature to a more tolerated range can damage the crystals. For the protection of the caveThe idea of ​​a request for the state of the place of the world heritage was hosted. It is possible that the cave is never open to the public.
