The formation of natural colored stone lines is due to the extrusion of lava during the crustal movement and change, which took tens of millions of years to form. The longer it calcifies underground, the richer the color of the stone will be. But at the same time, the longer the calcification time, the worse the hardness of the stone, and sometimes it will even be completely broken during mining. Therefore, it is extremely difficult to mine a complete stone.

The stones in each region are all of the same color, specific gravity and hardness, but all kinds of stones are not radioactive, and the stones in different regions are completely different. Its products have certain collection value.

The Environmental Protection Bureau has special instruments, and many units such as Geological Bureau and Earthquake Monitoring Bureau have monitoring instruments for geomagnetic radioactive elements. The real rainbow stone has no radiation and does no harm to human body.
