Shungite is a powerful stone to shield you from the electromagnetic radiation given off by electrical equipment, including computers, mobile phones, microwaves and televisions. It grounds spiritual energy to bring it into the Earth plane existence. Shungite is also used to bring Light into the auric energy field, allowing positive energy only to reach within that field. This brings not only physical protection but also psychic protection. It is said to be protection against the evil eye and negative energies. All our Shungite is a higher grade than black shale Shungite with 60-70% carbon content one grade lower than elite/noble.
