Shungite

Shungite is a true gift of nature to mankind. It consists largely of carbon, the basic building block of all life, and contains natural fullerenes. These unique molecular structures are described as radical scavengers and are the subject of intensive scientific research.
Its harmonizing properties bring us back to our inner center and strengthen our connection to other dimensions. It is also often mentioned in connection with electromagnetic fields.
Shungite is often placed near computers, technology rooms or high-voltage power lines, as it is said to absorb or shield radiation.
