Ever hear about the black, lustrous stone Shungite? Made of 98% carbon and even containing fullerenes (a special type of carbon consisting of a hollow cage of atoms, the first discovered being the buckminsterfullerene) the Shungite stone reportedly absorbs EMF radiation thus offering human health risk mitigation potential. Also the stone can structure water and is used in water purification techniques. Just another gift from nature that not many people are aware of!
