Roughly 1" across. Almost spheres, but not quite.
Shungite is a natural mineral with the crystal lattice or grid organized in a certain way, the basis of which is carbon. As we know, carbon is the basis of life on the Earth. Modern scholars view the emergence of life on our planet as a complex process of evolution of carbon compounds. They believe that these compounds can serve as a carrier of life in any part of the universe.
Shungite receives its healing power from one of its elements, fullerenes – a globular hollow molecule consisting of several dozens of carbon atoms. When fullerenes, a special molecular formation, were discovered in shungite a few decades ago, it became a sensation. Fullerenes, getting in our body, behave as the most powerful and most long-acting antioxidant as a means to fight free radicals. Today, doctors have great hopes for fullerenes.
The importance of this discovery is that until that time, scientists were aware only of three modifications of carbon - diamond, graphite and carbyne. The new molecule cuts diamond as oil, slows down the growth of cancer cells, and substances from fullerenes can slow down the activity of the AIDS virus. The discovery of the fullerene was a real breakthrough in nanotechnology and was declared a sensation of the 20th century. The scientists who have made it received the Nobel Prize in chemistry in 1996.
