The name tourmaline comes from “turmali” or “turamali” which is actually a Sinhalese name given to this fabulous stone from Sri Lanka by Dutch explorers in the early 18th century.
In Sri Lanka, a legend says that tourmaline comes from the sky and during its descent to earth, it would have crossed a rainbow which gave it its variations of colors. This explains the origin of its name meaning "the stone of a thousand colors".
In fact, tourmaline has been known for thousands of years. In the 3rd century BC, traces of this stone were found. In Greece, it was Alexander the Great (356-323 BC) who brought this stone back from his expeditions. However, tourmaline, due to its many colors, has very often been confused with other minerals.
Thus, there are very few legends or myths attached to this stone due to its late identification. However, some tourmalines have piezoelectric properties, which means that they have an electrical charge, negative at one pole and positive at the other pole. Tourmaline attracts particles to itself.
When the philosopher Theophrastus (-322 to -288) describes a stone having the ability to attract pieces of straw or pieces of wood, we understand that he is talking about tourmaline. Later in the 18th century, Dutch explorers used tourmaline to clean their pipes, because the stone attracted ashes.
As an anecdote, in the 16th century, a Spanish conquistador discovered a green tourmaline in Brazil, which he identified as an emerald. This discovery caused a rush in the Brazilian regions in search of these famous emeralds. The error was corrected in the 19th century and the emeralds were transformed into tourmalines.
Often mistaken for precious stones, tourmalines are therefore found in many jewels, and even in the British crown. We can also mention the Timur Ruby, a 352 carat jewel that was thought to be a ruby ​​until 1851 or the 170 carat Black Prince ruby ​​which is actually a tourmaline.
Tourmaline is increasingly attracting interest from connoisseurs and collectors. Thus, the Empress of China Cixi (1861-1908) loved this stone so much that she began to collect it. She asked for sculptures, brooches, watch clasps, rings, etc. to be made from it. Today, it rests on a cushion of tourmalines.
Tourmaline comes in various shades. They can also be bicolored or multicolor. There is a wide variety of tourmalines, of different colors, from opaque to transparent, with striated or hexagonal structures. It has a rhombohedral crystal system. It is an igneous and metamorphic rock that can come from hydrothermal deposits.
So, there are several types of tourmalines with various compositions such as magnesium silicates, sodium silicates, iron silicates, clay silicates, fluorides and borosilicate. Tourmalines are actually a whole family of stones, which have the same internal structure, but differ in chemical composition and therefore in color and appearance.
The main deposits are located in Brazil, Afghanistan, Australia, Brazil, Russia, Thailand, Burma, Madagascar, India, and the United States.

Black tourmaline is the most well-known variety of tourmaline. It is also identified as schorl. It is called black, but it can also be dark brown. It has gained its notoriety over time due to its many properties.
So black tourmaline, schorl, is the most common tourmaline and can sometimes measure up to 2 m high. Its composition very rich in iron gives it this black, opaque and intense appearance. We can emphasize that it is the only type of tourmaline with a uniform color.
Thus, schorl, a mineral species of tourmaline, belongs to the group of silicates, subgroup of cyclosilicates. The name "schorl" comes from German. It has a vitreous luster, with a conchoidal fracture, its line is white. It is a mineral from metamorphic rocks, leucogranites and pegmatites.
Like all tourmalines, schorl is composed of a complex silicate of boron, sodium, and aluminum and has a hardness of 7 to 7.5 on the Mohs scale. Its crystal system is rhombohedral. Schorl or black tourmaline occurs as elongated prismatic crystals, well formed and striated in the elongation or as small aggregates of small crystals.
Black tourmaline is a very ancient stone, cited in many traditions, notably among the Brazilians, Egyptians, Greeks and Indians. It is a stone renowned for its protective virtues. It is also an anchoring stone used today in lithotherapy and meditation. Due to its piezoelectric properties, black tourmaline is also used in electrochemistry.

The main deposits are located in Brazil, Madagascar, etc.

In Lithotherapy, tourmaline is a very powerful anchoring stone. It helps to keep your feet on the ground, calms scattered thoughts and refocuses attention. It soothes the mind and irrational fears. It allows you to connect to your inner self, to perceive deep needs and to identify the cause of certain blockages. These are often childhood traumas. It is an excellent meditation stone that channels the digressions of the mind.

Thus, schorl has strong protective virtues. It is able to absorb negative energies released by certain angry, jealous or envious people. It is said that it neutralizes harmful influences and is able to absorb electromagnetic waves. It is a stone of protection for both people and places. Placing various black tourmalines in the house, wearing a black tourmaline bracelet allows the person or home to be protected. This black stone removes the negative consequences of an unhealthy environment or waves from household appliances (telephone, computers, etc.).

Black tourmaline helps to divert bad thoughts, it improves concentration, creativity, inspiration and imagination. It is recommended for children or hyperactive people. It helps to find serenity and harmony. The wearer is calmer, less anxious and less anxious. He finds peace and wisdom.
