Shungite has metaphysical properties that make it useful for both healing and EMF protection.
Black is almost always the colour of protection in western magic. It is said to cloak the subject of the spell in darkness so that bad luck cannot find them.
The extremely dark colour of Shungite makes it the ideal stone for practices surrounding hiding from bad luck.
Because of its electricity-conducting properties, it is also suitable as an amplifier in magic and meditation and in boosting the power of electromagnetic fields. Strangely it has also been reported that it can help boost weak wi-fi signals, too.
