The difference between regular shungite and elite or noble shungite is in the proportion of organic carbon in it. Regular shungite contains from 35 to 60 per cent of organic carbon while the percentage of carbon in elite shungite is much higher and totals from 92 to 98 per cent.
Shungite in nutshell. Shungite cures, rescues, purifies, heals, protects, normalizes, restores and even stimulates the growth. Amazing rock: it kills and devours anything that harms people and other living beings, and concentrates and restores all that is good.
