The world we live in is a very fascinating place. Around the globe, there are places that have their own unique features. Features that are not just unique can also seem mind-boggling.
There are many mysterious places in the world, but none more compelling than the Cave of Crystals or Giant Crystal Cave, in Mexico. Deep down in the bowels of the Earth, the cave is a working mine that is popular for its extraordinary selenite crystals.
The extraordinary cave was discovered in 2000 by two brothers who were searching for fresh ore deposits in Naica Mountain, National Geographic reported. They came across an unexpected and awesome sight. Massive, milky-white crystals towered around them, filling a horseshoe-shaped cave.
