There is plenty of research to back up its ability to block EMF waves, etc.I bought a tester myself, tested the EMFs coming off the WiFi. Then I passed the large shungite cross I have in front of the WiFi and the reading plummeted. I took video of it. Also, I have elite shungite chunks that I put into my water filter tower. I can’t say for certainty if it was the shungite, but my ulcer I gave myself from late nights with steaks on the Traeger washed down with moonshine was remedied that month. Do research it. It makes for beautiful jewelry as well
