TOPIC 01: Black Tourmaline... Want Powerful Protection Against Negative Energy?

Black Tourmaline crystal is a powerful stone for protection against negative energy of all kinds... as well as being a strong spiritual grounding stone. This is one of the most popular crystals to be used for metaphysical purposes. Many people, and I am amongst this group... believe this is the best protection stone that you can use. It is powerful for healing and for psychic protection and spiritual purposes... and will strengthen the immune system and help allergies. It encourages positive attitudes, good luck and happiness, regardless of the circumstances that you find yourself in. They are wonderful aids to both the professional healer and the average person who wants a stone that will be a positive force for good in your life... as it creates a positive attitude and mindset.

Why Would You Use It

Black Tourmaline crystals are strong stones of the two lowest chakras, which are the earth star chakra and the base chakra... as they are powerful stones for grounding. You all have times when you feel negative... or when you encounter other people who are giving off vibrations that are not pleasing to you. It will also act to protect you against psychic attack and negative entities. In addition these stones will purify the area where they are located. You all live with a lot of electro-magnetic smog... including your televisions, computers and the large number of other electrical devices that seem to be essential these days, just to live your life.
One of the most powerful things about Black tourmaline is that it will suck up any negativity or disharmony that it encounters from its surroundings. But it does not absorb it... but will transmute... or convert the negative energy into positive energy.

How To Use It

Although wearing stones as jewelry is the easiest way to keep a piece of the stone on your body, if this is not possible keep a piece of the stone in the room with you... as this is very helpful. Once you have learned easy meditation techniques, you may also wish to use one of these stones in meditation. They will help you to let go of negativity and self doubts or any feelings of anxiety or negativity of any kind. For spiritual grounding and during a grounding meditation these are a wonderful ally in the process.

It is easy to buy a piece of Black Tourmaline stone... and having the vibration of it within your aura for as long as possible is to your advantage. If it is not possible for you to have them on you during the day... it would be advantageous, to at least have a couple of these stones in the bedroom.

Putting one of these crystals under your pillow will cleanse your etheric body while you sleep... as well as the room where you are sleeping. It will strengthen the immune system and assist pain relief of arthritis... and the relief of spinal or muscular problems.

The good thing about this stone is that it does not absorb negativity... but changes or alters it or transmutes it into positive energy. This means it improves the vibration of the air where it is located. Keeping it in the bedroom will help you to sleep better and wake more refreshed.

Where Does It Come From

Black Tourmaline has been found in a large number of locations... including Pakistan, Australia, Brazil, Sri Lanka, Africa and the USA.

It is also known as Schorl Tourmaline. Although it is known as the black variety of tourmaline... not all of the black stones are black... but are a very dark blue color... although it is hard to tell the difference.

This is a powerful asset to your health, as it not only removes the negative energy but by changing it to positive energy it has an excellent effect on your well-being!

Wearing This Black Stone

Keeping a piece of this stone on you at all times is highly recommended. Although Black Tourmaline jewelry is not as common as the other colors of Tourmaline... it is possible to buy very nice pendants made from the stone. One of the reason it is not so common, is because much of this stone is not stable enough to cut into cabochons... but the Australian stone is highly stable. Lovely Black Tourmaline pendants can be bought... including nice pieces made from Australian stone... or pendants that are rough stones set in silver or even beads. Whatever type you buy, wearing it is very beneficial.

The solid and stable stone from the Flinders Ranges in Australia, can be cut into lovely checker cut pieces... like the one in the photo... and they make beautiful pendants. As jewelry made from these black stones is becoming available, these powerful black stones are now on the Zodiac Birthstones list. They are also a Capricorn birthstone so you may find lovely Birthstone jewelry containing this stone. I know that there are stones that send back the negative energy... but this stone will not do that. Even though some people believe Black Tourmaline will do that... instead it changes it to positive energy.
The best stone to use to send negative energy back to where it came from is Fire Agate... especially Crackled Fire Agate.
Who Should Use It

Stress is so prevalent amongst all of us... that we all should probably have a piece of Black Tourmaline... as they supply useful ways to relieve stress. Tourmaline will help you to release stress, and if you are prone to obsessive behavior, it is a powerful ally to help you to disconnect from these activities.
Some time ago, scientists came out in the media discussing the issues around the vibrations emanating from electrical devices and cell phones.

The discussion centered around the negative effect on your body's electrical system, that these emit.

It was recommended for that reason that you should try to have your nights rest in an area where you have as few electrical devices as possible. This is hard to do. Adding some Black Tourmaline crystals to the bedroom will aid you to regulate your body's electrical system. If you do a lot of spiritual work, or have strong psychic powers and you use these abilities quite a lot... you may become ungrounded. Black Tourmaline will also ground you quite quickly.This is one of the stones that I always keep in my pocket... or wear as jewelry, along with a few others, both for psychic protection and grounding.If you acquire a small cloth bag... and many crystal shops sell them, you can put your crystals in your pocket easily each day.

TOPIC 2: Tourmaline is a crystal boron silicate mineral compounded with elements such as aluminium, iron, magnesium, sodium, lithium, or potassium. Tourmaline is classified as a semi-precious stone and the gem comes in a wide variety of colors. The name comes from the Sinhalese word "Thuramali" or "Thoramalli" , which applied to different gemstones found in Sri Lanka.

Brightly colored Sri Lankan gem tourmalines were brought to Europe in great quantities by the Dutch East India Company to satisfy a demand for curiosities and gems. At the time it was not realised that schorl and tourmaline were the same mineral.

Tourmaline species and varieties
Dravite species: from the Drave district of Carinthia Dark yellow to brownish black—dravite

Schorl species: Bluish or brownish black to Black—schorl

Elbaite species: named after the island of Elba, Italy Red or pinkish-red—rubellite variety (from ruby)
Dark black—schorl (from indigo)
Light blue to bluish green—Brazilian indicolite variety
Green—verdelite or Brazilian emerald variety
Colorless—achroite variety


The most common species of tourmaline is schorl. It may account for 95% or more of all tourmaline in nature. The early history of the mineral schorl shows that the name "schorl" was in use prior to 1400 because a village known today as Zschorlau (in Saxony, Germany) was then named "Schorl" (or minor variants of this name). This village had a nearby tin mine where, in addition to cassiterite, black tourmaline was found. The first description of schorl with the name "schürl" and its occurrence (various tin mines in the Saxony Ore Mountains) was written by Johannes Mathesius (1504–1565) in 1562 under the title "Sarepta oder Bergpostill".[3] Up to about 1600, additional names used in the German language were "Schurel", "Schörle", and "Schurl". Beginning in the 18th century, the name Schörl was mainly used in the German-speaking area. In English, the names shorl and shirl were used in the 18th century. In the 19th century the names common schorl, schörl, schorl and iron tourmaline were used in the Anglo-Saxon area.[3] The word tourmaline has two etymologies, both from the Sinhalese word turamali, meaning "stone attracting ash" (a reference to its pyroelectric properties) or according to other sources "mixed gemstones".

Black Dravite on a grey matrix
The name dravite was used for the first time by Gustav Tschermak (1836–1927), Professor of Mineralogy and Petrography at the University of Vienna, in his book Lehrbuch der Mineralogie (published in 1884) for magnesium-rich (and sodium-rich) tourmaline from the village Unterdrauburg, Drava river area, Carinthia, Austro-Hungarian Empire. Today this tourmaline locality (type locality for dravite) at the village Dravograd (near Dobrova pri Dravogradu), is a part of the Republic of Slovenia.[4] Tschermak gave this tourmaline the name dravite, for the Drava river area, which is the district along the Drava River (in German: Drau, in Latin: Drave) in Austria and Slovenia. The chemical composition which was given by Tschermak in 1884 for this dravite approximately corresponds to the formula NaMg3(Al,Mg)6B3Si6O27(OH), which is in good agreement (except for the OH content) with the endmember formula of dravite as known today.[4]

A lithium-tourmaline (elbaite) was one of three pegmatitic minerals from Utö, Sweden, in which the new alkali element lithium (Li) was determined in 1818 by Arfwedson for the first time.[5] Elba Island, Italy, was one of the first localities where colored and colorless Li-tourmalines were extensively chemically analysed. In 1850 Rammelsberg described fluorine (F) in tourmaline for the first time. In 1870 he proved that all varieties of tourmaline contain chemically bound water. In 1889 Scharitzer proposed the substitution of (OH) by F in red Li-tourmaline from Sušice, Czech Republic. In 1914 Vernadsky proposed the name Elbait for lithium-, sodium-, and aluminum-rich tourmaline from Elba Island, Italy, with the simplified formula (Li,Na)HAl6B2Si4O21.[5] Most likely the type material for elbaite was found at Fonte del Prete, San Piero in Campo, Campo nell'Elba, Elba Island, Livorno Province, Tuscany, Italy.[5] In 1933 Winchell published an updated formula for elbaite, H8Na2Li3Al3B6Al12Si12O62, which is commonly used to date written as Na(Li1.5Al1.5)Al6(BO3)3[Si6O18](OH)3(OH).[5] The first crystal structure determination of a Li-rich tourmaline was published in 1972 by Donnay and Barton, performed on a pink elbaite from San Diego County, California, USA.

Chemical composition of the tourmaline group

The tourmaline mineral group is chemically one of the most complicated groups of silicate minerals. Its composition varies widely because of isomorphous replacement (solid solution),.

Physical properties

Crystal structure
Tourmaline belongs to the trigonal crystal system and occurs as long, slender to thick prismatic and columnar crystals that are usually triangular in cross-section. The style of termination at the ends of crystals is asymmetrical, called hemimorphism. Small slender prismatic crystals are common in a fine-grained granite called aplite, often forming radial daisy-like patterns. Tourmaline is distinguished by its three-sided prisms; no other common mineral has three sides. Prisms faces often have heavy vertical striations that produce a rounded triangular effect. Tourmaline is rarely perfectly euhedral. An exception was the fine dravite tourmalines of Yinnietharra, in western Australia. The deposit was discovered in the 1970s, but is now exhausted. All hemimorphic crystals are piezoelectric, and are often pyroelectric as well.

Tourmaline gemstones - Mozambique
Tourmaline has a variety of colors. Usually, iron-rich tourmalines are black to bluish-black to deep brown, while magnesium-rich varieties are brown to yellow, and lithium-rich tourmalines are almost any color: blue, green, red, yellow, pink, etc. Rarely, it is colorless. Bi-colored and multicolored crystals are common, reflecting variations of fluid chemistry during crystallization. Crystals may be green at one end and pink at the other, or green on the outside and pink inside; this type is called watermelon tourmaline. Some forms of tourmaline are dichroic, in that they change color when viewed from different directions.

Physics explains color in terms of the wavelength of radiation. A spectrograph that only identifies the position of spectral lines will perfectly differentiate between a radiation at 0.530 µm and another at 0.532 µm, where our eyes will only perceive the same green.

The pink color of tourmalines from many fields is the result of a continued natural irradiation. During their growth, these tourmalines incorporate Mn2+, whereas initially they are by nature very pale. Their granitic environment exposes to them a natural gamma ray exposure due to radioactive decay of 40K, causing the gradual formation of the Mn3+ ions responsible for a pink to red color.[citation needed]


Some tourmaline gems, especially pink to red colored stones, are altered by irradiation to improve their color. Irradiation is almost impossible to detect in tourmalines, and does not impact the value. Heavily-included tourmalines, such as rubellite and Brazilian paraiba, are sometimes clarity-enhanced. A clarity-enhanced tourmaline (especially paraiba) is worth much less than a non-treated gem.[7]


Tourmaline is found in granite and granite pegmatites and in metamorphic rocks such as schist and marble. Schorl and lithium-rich tourmalines are usually found in granite and granite pegmatite. Magnesium-rich tourmalines, dravites, are generally restricted to schists and marble. Tourmaline is a durable mineral and can be found in minor amounts as grains in sandstone and conglomerate, and is part of the ZTR index for highly-weathered sediments.

Tourmaline localities

Gem and specimen tourmaline is mined chiefly in Brazil and Africa. Some placer material suitable for gem use comes from Sri Lanka. In addition to Brazil, tourmaline is mined in Tanzania, Nigeria, Kenya, Madagascar, Mozambique, Namibia, Afghanistan, Pakistan, Sri Lanka, and Malawi.[8]

Some fine gems and specimen material has been produced in the United States, with the first discoveries in 1822, in the state of Maine. California became a large producer of tourmaline in the early 1900s. The Maine deposits tend to produce crystals in raspberry pink-red as well as minty greens. The California deposits are known for bright pinks, as well as bicolors. During the early 1900s, Maine and California were the world's largest producers of gem tourmalines. The Empress Dowager Tz'u Hsi of China loved pink tourmaline and bought large quantities for gemstones and carvings from the then new Himalaya Mine, located in San Diego County, California.[9] It is not clear when the first tourmaline was found in California. Native Americans have used pink and green tourmaline as funeral gifts for centuries. The first documented case was in 1890 when Charles Russel Orcutt found pink tourmaline at what later became the Stewart Mine at Pala, San Diego.[10]

Almost every color of tourmaline can be found in Brazil, especially in the Brazilian states of Minas Gerais and Bahia. In 1989, miners discovered a unique and brightly colored variety of tourmaline in the state of Paraíba. The new type of tourmaline, which soon became known as paraiba tourmaline, came in unusually vivid blues and greens. These colors were often described as "neon" since they appeared to glow. Brazilian paraiba tourmaline is usually heavily included. Much of the paraiba tourmaline from Brazil actually comes from the neighboring state of Rio Grande do Norte. Material from Rio Grande do Norte is often somewhat less intense in color, but many fine gems are found there. It was determined that the element copper was important in the coloration of the stone.

In the late 1990s, copper-containing tourmaline was found in Nigeria. The material was generally paler and less saturated than the Brazilian materials, although the material generally was much less included. A more recent African discovery from Mozambique has also produced beautiful tourmaline colored by copper, similar to the Brazilian paraiba. While its colors are somewhat less bright than top Brazilian material, Mozambique paraiba is often less included and has been found in larger sizes. The Mozambique paraiba material usually is more intensely colored than the Nigerian. There is a significant overlap in color and clarity with Mozambique paraiba and Brazilian paraiba, especially with the material from Rio Grande do Norte. While less expensive than top quality Brazilian paraiba, some Mozambique material sells for well over $5,000 per carat, which still is extremely high compared to other tourmalines.
Tourmaline mineral
Another highly valuable variety is chrome tourmaline, a rare type of dravite tourmaline from Tanzania. Chrome tourmaline is a rich green color due to the presence of chromium atoms in the crystal; chromium also produces the green color of emeralds. Of the standard elbaite colors, blue indicolite gems are typically the most valuable, followed by green verdelite and pink to red rubellite.[citation needed] There are also yellow tourmalines, sometimes known as canary tourmaline. Zambia is rich in both red and yellow tourmaline, which are relatively inexpensive in that country. Ironically the rarest variety, colorless achroite, is not appreciated and is the least expensive of the transparent tourmalines.


Extra fine indicolite (blue tourmaline) and verdelite (green tourmaline) are found in the Nuristan region (Ghazi Abad district) and Pech Valley (Pech and Chapa Dara districts) of Kunar province. Gem-quality tourmalines are faceted (cut) from 0.50–10 gram sizes and have unusually high clarity and intense shades of color.
