The predatory appearance of this stone seems to warn of the danger hidden inside it. However, more than one hundred people were destined to die before the secret of the mineral was revealed.

This mineral is most often associated with liquid, which has a sharp characteristic odor. It can be obtained from manure. However, this is no obstacle for making from it candies popular in Europe.

This stone is the official symbol of the American state of Colorado. However, its appearance is more like a flower than a mineral.

In the second half of the 19th century, art iron casting became the trademark of the Urals and gained wide recognition around the world.

This rare and beneficial mineral is composed of almost an entire periodic table. However, there are very few deposits where it can be mined — less than a dozen in the whole world, with the largest one located in Russia.

This stone is a real treasure of the Hermitage. Yet there is a place on Earth where the mineral literally lies underfoot.
