Natures Artifacts Inc
Shungite is a black, lustrous, non-crystalline mineraloid consisting of more than 98 weight percent of carbon. It was first described from a deposit near shunga village, in karelia, russia, from where it gets its name.
Shungite has been used in medical treatment since the early 18th century. Peter the great set up russia's first spa in karelia to make use of the water purifying properties of shungite, which he had himself experienced. He also instigated its use in providing purified water for the russian army. The anti-bacterial properties of shungite have been confirmed by modern testing."
