This rare black stone conducts electromagnetic energy making it great for protection from those vibrations emitted by our computers, microwaves, TV's & Wi-Fi's. It absorbs and deflects negative eenrgy as well and needs to be cleansed on a regular basis. This crystal comes from Russia and is related to the root chakra, however its higher vibrational frequency allows it to work on all the chakra centers equally as well. Shungite helps the body rid itself of pollutants.  It has purifying energies that aid the immune system, the skin and is cooling for inflammatory conditions. Our current stock is approx 3/4 of an inch in size.(about the size of a nickle- sorry, prices have substantially gone up since our last order with our suppliers)
