One of the most dangerous minerals on the planet is chalcanthite. When water hits it, it also turns into a monster that can kill all living things around. With this chemical reaction, toxic copper vapors are released, which affect the internal organs. Sometimes the stone is also called “copper sulfate”.
At the same time, he is incredibly handsome. The arrangement of the crystals resembles a blue rose transparent to the light. But when heated, its “glassy” properties disappear. It has five molecules of water per molecule of copper. And when the water evaporates, the gem becomes brighter.
It was first discovered in Chilean mines and described by an employee of the University of Munich, professor of mineralogy Wolfgang Ksawer Franz von Kobell in 1853. In the caves of the Andes, it is still not uncommon, mainly in the form of stalactites.
