Elite Shungite is the only known natural mineral to contain fullerenes, a crystalline form of carbon. This powerful stone can heal and protect you at the same time. Since Shungite works with your Root Chakra, it will ground you to Mother Earth and her energies, which in turn can reflect electromagnetic frequencies and harmful environmental toxins. It is a great tool for meditation, placing near your computer or electronics, or purifying your water. Approximate Measurements: 3 inches x 2 inches
