Tourmaline is not just one stone, but a whole subgroup of minerals similar in composition and structure and belonging to a group of boron-containing aluminosilicates.
"Electrical Mineral" - that's what tourmaline Pierre Curie and Marie Sklodowska-Curie called, finding in it the presence of a constant electric charge, whose radiation at its power( 0.06 mA) corresponds to the radiation of cells of the human body.
Externally, tourmaline crystals are convex triangular elongated prisms with characteristic glass shine and longitudinal pronounced shading along their main axis.
The name "tourmaline" comes from the Sinhalese "tourmal", which in translation means "a magical multi-colored stone".
And indeed, these gems surprise with a variety of their colors.to table of contents ^

Chemical composition and physical properties of
stone As part of tourmaline - more than 25 trace elements from Mendeleyev's table, including:
- fluorine, etc.
The main feature of this boron-containing aluminosilicate is its variable chemical composition.
All tourmalines have a sufficiently high hardness( 7-7.5 on the Mohs scale) and density( 3-3.25 g / cm3).
The peculiarity of the crystals of tourmaline is their asymmetric faceting from different ends( hemimorphism), due to which their special pyro- and piezoelectric properties are manifested.
It is thanks to these properties that today tourmaline is actively used for healing.to contents ^
Therapeutic properties of tourmaline
The piezoelectric properties of these minerals manifest themselves in their ability to heat( solar or heat of the human body), form negative electric charges. These electrical charges, connecting with oxygen atoms, form negative aeroions - unique particles that activate the energy capabilities of the body.
Scientists have proven that air ions have a positive effect on:
- blood sugar;
- blood pressure;
- tissue respiration;
- the work of the nervous system;
- body temperature;
Aeroions have an effect on all the basic physico-chemical processes that occur in the body.
Under their action in the human body, the following changes occur:
- local blood flow improves;
- is strengthened by immunity;
- hormone and endocrine systems are restored;
- is enhanced by cellular metabolism;
- improves nutrition in organs and tissues;

- improves complexion;
- restores the sexual function of the body;
- improves potency;
- is recovered from stressful situations by the nervous system;
- fades away dizziness;
- relieves headaches;
- improves eyesight.
During heating, tourmalines emit thermal long-wave infrared rays with a range of 6-14 microns, corresponding to weak currents flowing in the human body. The Japanese call them "the rays of life."These rays help restore the energy balance of a person.
Due to the high bioenergetic activity in alternative medicine, tourmaline is actively used in:
- infectious diseases;
- oncological diseases;
- diseases of the nervous system;
- diseases of the endocrine system;
- decreased immunity;
- metabolic disorders;
- blood diseases;
- of prostate disease;

How to distinguish natural tourmaline from forgery
Tourmalines falsify quite often, offering instead of natural stones imitations from the most common glass and synthetic analogues of gems.

- Test it for strength by trying to scratch it. Tourmaline is a very hard mineral, twice as strong as glass, so you can not scratch anything on it.
- Pay attention to the game of light. Natural tourmaline is characterized by birefringence and strong pleochroism.
- Make sure that the mineral is electrified by doing a small experiment. When heated, the natural gem begins to become electrified. Try it at a time when it will become warm, bring to it small pieces of paper. If they start to attract - it's definitely not fake before you. Electrification is the main feature of tourmaline.
