More than ever we can benefit from shungite for EMF protection, as well as, WiFi. Here we have Mobile Phone Shungite. These are stuck on the back of mobile phones with the phone cover protecting it from falling off and to protect it from knocks. The white thing on the main photo is the sticker.
Buy the Shungite book to see the healing properties. And what energy tests were done to prove that shungite is more effective than other stones at blocking WiFi etc.
Energetically Shungite strengthens your aura against the draining effect of mobile phones. I experienced this unexpectedly in aura photos taken while I had the phone in my pocket. And when I got my husband to hold it showing there was a definite difference. I feel its so busy help with phone that it will not do much if any other energetic help. From time to time place it (and the phone) on amethyst to receive some re-charging help and connection to its crystal friends.
