Shungite is a black, lustrous, non-crystalline mineraloid consisting of more than 98 weight percent of carbon. It was first described from a deposit near Shunga village, in Karelia, Russia, from where it gets its name.
Shungite attenuates electromagnetic emissions from electrical grids, computers, cell-phones, Wi-Fi, appliances, and other electronic devices—meaning shungite transforms harmful manmade EMFs into waveforms that are more compatible with our biology.” It can purify water. This is all due to the crystal's carbon content.
 
Quartz crystal is considered a “master healer.” It's said to amplify energy by absorbing, storing, releasing, and regulating it. It's also said to aid concentration and memory. Physically, clear crystals are claimed to help stimulate the immune system and balance out your entire body.
