Scientists estimate the age of shungite to be almost 2 billion years. Though it is similar in appearance to coal, it is found in very ancient layers of the Earth’s crust that
were formed when there were no life forms on the Earth.

Where did this strange rock come from? At that time there were no forests to form carbides such as coal. Experts claim there were only protobacteria living in an oxygen-free atmosphere.
But suddenly huge deposits of this marvelous mineral seem to have
appeared.

Who gave them to the man? Why? How? The answers
to the first two questions are quite simple. Having foreseen the
trap that man would be driven into by civilization’s “achievements,” God
showed the way out. He made shungite to heal and rescue life on the
earth. It is not in vain that some prophets point to the North as
the place of rescue from environmental disasters. Karelia, in the
north of Russia is known to have the only shungite filed in the world.

The answer to the third question comes from science. There are at least three theories to explain shungite’s origin:

• Primitive microscopic organisms existed in shallow bays of the ancient sea. Sea scurf rich in these organic remains formed a material that produced shungite.
• According to another rather exotic version, shungite is a part of a gigantic meteorite that brought a part of a decomposed planet called Phaeton to the Earth. Phaeton is
  believed to have had carbon-based life forms. The gigantic fragment
  brought them to earth and formed the shungite field in the area
  of impact.
• Some researchers assert that the form and structure of shungite have volcanic features. The volcanic ejection of the shungite substance would have played the same role as
  the hypothetical Phaeton fragment.

Whichever of these theories may hold the truth, it cannot be disputed that shungite with its unique healing qualities and abundance of remarkablecharacteristics, is a mineral like
nothing else on earth

Shungite has the ability to clean water from almost of all organic compounds (including pesticides), metals, bacteria and harmful microorganisms. Water
from Lake Onega in Russia, can be used for drinking without any prior
cleaning! It is the result of thousands of years of interaction with
Shungite. Commercial use of Shungite filters started back in 1990’s,
during that time there were conducted many experiments and studies on
Shungite influence on the human body. Scientists came to conclusion
that Shungite water is absolutely non-toxic. It was also proven that
shungite water can be used without any prior boiling! The water has strong antibacterial ability.
During the experiments, water was contaminated with streptococcus of
groups A and D. Experiment showed that only after half an hour in
Shungite water the concentration of streptococcus group D decreased by
the factor of 100 and group A by the factor of 900! Shungite
cleans water of various chlorine compounds, nitrates, copper,
magnesium, iron, cleans up visually dirty water, eliminates sour taste.
Shungite removes heavy metals, chlorine, enriches drinking water in
potassium.

Use of shungite water is recommended for the treatment of the following illnesses:
- Impotence
- Anemia
- Allergies
- Asthma
- Gastritis
- Dyspepsia
- Kidney diseases
- Liver diseases
- Diabetes
- Gall-bladder problems
- Immune system deterioration
- Pancreas diseases
- Common colds
- Cardiovascular diseases
- Cholecystitis
- Chronic fatigue.

Put the Shungite stones on the bottom of a 3-leter water. After 48 hours the water will be biologically active.
It ‘s ready for external and internal use. You should put shungit
stones on sun light every month and replace the stones every 6 months.
Not only does water infused with Shungite becomes ultra clean; it also
becomes a colloidal solution of hydrated fullerenes, which are an
essential part of the new generation of drugs. One of the examples is
the antihistaminic effect of Shungite water. After
the use of Shungite water there is a dramatic decrease of histamine in
blood stream, thus causing a serious decrease in allergies. It is
recommended to drink at least 2-3 glasses of Shungite water a day to
cure or prevent digestive, muscular or neural system illnesses and to
increase circulation of blood. Daily use of Shungite water to wash face
or body improves elasticity of skin, gives it a healthy look. Also it
helps the drinker to forever get rid of acne, skin redness and other
skin problems. Shungite water helps with hair loss. It strengthens hair
roots and fights dandruff. Shungite water helps curing burns, cuts,
callosities, arthritis, osteoarthritis and varicose veins. Simple
mouthwash with Shungite water will cure sore throat, stomatitis, colds
and tonsillit

Shungite has a lot of other different properties, have a look here:

I have personally used shungite filtered water for past 2 years, I have noticed that since I strated drinking the water, the number of colds and other respiratory illnesses has gone down significantly not just for myself, but also for my entire family, including small children. I also wear shungite  necklace all the time to protect myself from exes of electro-magnetic waves. I really am very fond of this stone :)
