A unique characteristic of real shungite is that it's conductive, i.e., it conducts electricity. I tested this beautiful shungite square with an ohmmeter per instructions by Gary Fong and it conducts perfectly. If you touch the two leads of an ohmmeter together without anything in between, the meter will read zero - indicating there's a complete electrical circuit with no resistance. Touching the two leads to opposite sides of this shungite square causes the ohmmeter to go to zero, which indicates no resistance to the flow of electricity through the square. Low to zero Ohms means low to no resistance. So, this square is a perfect conductor like real shungite should be. I bought this item planning to return it if it failed this test. I was ecstatic with the result as I didn't want to return it once I saw it. It's a very beautiful, unique and intriguing decorative item, unlike anything I've ever had. But I bought shungite for a reason and needed to know if it was real. I also purchased a large 220 gm elite shungite nugget and a large 6 inch sphere and they also tested very well. I believe you can trust that Shungite Queen's items are indeed high-quality authentic shungite and I'm happy with my purchases.
