Just over 2300 years ago, a prominent philosopher had a special fascination with gemstones, their characteristics and powers. Theophrastus was the first to decide to report all his research and theories on minerals. He knew and appreciated the most beautiful gemstones and gems that have occupied a very important place in the history of mankind and its main characters.
Teophrastus was also interested in Tourmaline, which surprised him even more, because he could one day see that this crystal attracted straw, ashes or small pieces of wood if heated, thus revealing its pyroelectric characteristic. It is because of this that the Dutch baptized it in the 18th century: "asshentrekker" (ash band). Its official discovery dates back to 1400 B.C., in a town now known as Zschorlau, Germany, from where it got its name "Schorl". This town had a tin mine in its vicinity, where not only Cassiterite but also Black Tourmaline stone could be found. It was first called Schürl until 1600.
It is said that the great magicians of antiquity invoked this gem to protect themselves from the demons that escaped to Earth. It is probably these ancient legends that make it still present today, so inescapable and so famous in the world of protection against evil entities evolving on earth. It was long believed that the stone of the Kaaba was composed of Tourmaline. But it seems that it is in fact an Obsidian, although no scientific study is able to confirm this, since the analysis of the Kaaba is not free.
In 18th century literature, the writer Barbara Walker cites references that establish that this stone was beneficial to artists, authors, actors and creators. In the same century, a Dutch scientist claimed that a Tourmaline stone wrapped in silk and placed against the cheek of a feverish child would induce sleep. India also worshipped this gem. It was used as an information and help tool to discover what was good and positive and also what was not, in order to be always vigilant. It was also used to reveal the cause of difficulties or dysfunctions.
The gem was also highly valued by alchemists who, perhaps because of its pyroelectric effect, considered it to be related to the philosopher's stone. They believed that it was this stone that would confer enlightenment, give power over spiritual matters, unite opposites, and transmute base metals into pure gold. Even today, this stone is still used by African, Native American and Aboriginal tribes in Australia as a protective talisman, protecting against all dangers.
Its origin is magmatic in granite and pegmatite; hydrothermal in grisene, quartz veins and metalliferous; metamorphic in migmatite, gneiss and mica schist. It is generally associated with Moscovite, Quartz and Albite. Perfect crystals exist in many pegmatite sites. They occur as long prismatic crystals measuring up to 5 meters at the Arendal site in Norway. Perfect crystals are also found at Kaatiala in Finland, Dolni Bory in the Czech Republic and Coselheira Pena and Galileia in Brazil.
Given the chemical complexity of this mineral, there are multiple varieties that form ranges between them. 33 mineral varieties are included in the Tourmalines group according to the International Mineralogical Association, such as :
- Acrobate (colorless and very rare) ;
- Buergerita or Fluor-buergerite (in homage to the American M. S. Buerger, with a bronze, brown or black tonality) ;
- Chromdravite (dark greenish);
- Chromiferous (green, very rare);
- Dravite (from Drava in Carinthia, of a yellow to dark brown color) ;
- Elbaite (from the island of Elba in Italy), of very variable hues and whose variety "Moorish head" has a blackened end;
- Feruvite (dark brown);
- Foitite (dark indigo, purple) ;
- Hydroxyuvite (orange) ;
- Indicolite (indigo with duck blue tones, very popular) ;
- Liddicoatite (in homage to the gemmologist Liddicoat, light brown, pinkish to red, greenish, blue, rarely white);
- Olenite (light pink);
- Paraiba (commercial name used for the blue-green Elbaites, discovered in the state of Paraiba in Brazil in 1987, its turquoise blue and neon blue tones would be due to manganese and copper. They are highly sought-after) ;
- Povondraite (black);
- Rossmanite (pale pink, pinkish) ;
- Rubellite (pinkish to red, the most sought-after being raspberry red); Santa Rosa (emerald green) ;
- Schörl (black);
- Schorl-f (pale brown, grey-brown) ;
- Siberite (pinkish-lilac to blue-violet tones) ;
- Tsilaisite (from a city in Madagascar, yellow tinged) ;
- Uvite (from the province of Uva in Sri Lanka, greenish or blackish) ;
- Vanadiumdravite (greenish);
- Verdelite (green, the most common) ;
Like a diamond, this gem has signs that make it not only found in jewelry. Its pyroelectric faculties, for example, cause the accumulation of opposite electric charges at its ends when it is heated. It can be used to attract dust or small pieces of paper, for example. It is therefore used in some equipment to eliminate static electricity. These stones are distinguished by their vitreous luster and a wide variety of colors. The pinkish tones of some of them present in several deposits are the result of constant natural irradiation.
During their formation, these minerals incorporate manganese (Mn2+), whereas they are originally very pale in color. Their granitic environment exposes them to natural gamma rays due to the decay of radioactive potassium (40K). This reaction causes the gradual formation of manganese (Mn3+), the ions that carry the pink to red colors.
Insoluble in acids, they develop hexagonal prismatic crystals with alternating wide and narrow faces, forming a fairly triangular section. According to Strunz's classification, Tourmalines form a group noted 9.CK.05: they are silicates (9), more precisely cyclosilicates (9.C) with six-membered rings (Si6O18) with complex island anions (9.CK).
According to the classification of Dana (American geologist and mineralogist), they are classified in several groups according to their composition: they all belong to the cyclosilicates containing six-membered (Si6O18) rings, in which silicon can be replaced by aluminium and can contain OH hydroxyl (designated 61). A distinction is made between those that are deficient in alkali metals (class 61.03a) and those that are deficient in calcium (class 61.03b), lithium (class 61.03d), sodium (class 61.03e) and iron (class 61.03c).
In fact, the name "Tourmaline" includes many minerals of the silicate family. In its natural state, the stone often comes in the form of rods. It is common to encounter them with small cracks, sometimes wavy, but also perpendicular. Its section is shaped like a triangle with curved faces. Etymologically, the term "Tourmaline" derives from Sinhalese, the language spoken in Sri Lanka, "thuramali", literally: the stone of a thousand colors.
Tourmaline Meaning and Properties
Tourmaline Metaphysical Properties
It has the ability to absorb all positive vibrations. On a psychological level, it is an excellent ally for those who practice meditation because it helps to calm emotions and stress situations. It avoids states of sadness, keeping it at bay by creating an impassable energy field.
By studying the benefits of Tourmaline, we can deduce that it would be ideal for people with extraordinary abilities to perceive the paranormal energies in their environment, because in addition to absorbing negative energy, it can also help control the effects caused by fear.
Tourmaline Healing Properties
The power of this mineral not only has a very positive influence on well-being and mental health, but also on the body. It influences the balance in various aspects of the body's functioning, especially in the processes of care. Experimentally, it is used to eliminate pain, rid the body of toxins and balance the endocrine system, relieve stress in case of pain and physical disorders. Once again, these processes are intimately linked to the pyroelectric and piezoelectric faculties of the stone. It also relieves stress.
This stone produces weak infrared rays with energetic and calorific virtues of analgesic effects. In contact with the skin, a natural heat spreads which, thanks to its relaxing action, soothes muscle, joint and ligament pain. In addition, this stone has qualities that affect magnetic fields. It can be used to reduce the negative effects of electromagnetic waves from household appliances.
For people sensitive to the nuisances produced by electromagnetic waves, this gem will simplify their life. Sensitive to perfumes, perspiration and household products, this stone is also used in cosmetics in the manufacture of perfumes. Often polished by hand, it can be used in different ways as jewelry. It can easily be carried in a trouser pocket, jacket pocket or even in a handbag.
If we talk about physical health, it is inevitable to refer to its ability to help balance and unblock the chakras, which makes it a very good support for the practice of Reiki. Tourmaline is linked to the root chakra, which is essential for stability, anchoring and rooting. Some experts believe that it is very useful to place it on the skin at the level of the solar plexus to help balance this area.
Another inescapable fact is its ability to transfer energy from a positive to a negative pole, and vice versa. This seems to be an extraordinary faculty, however, the person who wears it will have to remain vigilant and protect it from the glances or frictions of unknown or "enemy" people. To purify it, place the stone within the burning incense smoke and visualize the negative forces emanating from the stone by following the path of the incense smoke.
