Dravite stone (brown tourmaline) - properties and magic of the mineral

Even non-precious stones can be very beautiful and have unique properties for which true collectors and specialists value them. Dravite can be classified as one of these stones. In itself, this is not an independent mineral; it is one of the existing such popular stones as tourmaline. It has many unique properties, which will be discussed below.

A story about scientists and sailors

Pliny the Elder mentions tourmaline under the name “lychnida”.

Moreover, the scientist distinguishes between varieties of the mineral:

“one that sparkles with purple, the other that is a scale, heated by the sun or the friction of the fingers, they attract chaff and fibers of paper.”

Biruni does not write about tourmaline as an independent mineral.

In an Armenian manuscript from the 18th century. the stone “tirmil” is mentioned - red-green in color.

Red tourmalines in Russia were used to decorate church utensils.

Gems came to Europe from Ceylon. Dutch sailors, who transported cargo from Ceylon to Europe, noticed the beneficial properties of pebbles. They attracted ashes. Those who like to smoke a pipe cleaned their “nose warmers” with the help of gems. And they even gave the stone its name. "Aschentrekker" - " pulling ashes ."

origin of name

Tourmaline - Turmalin - Tourmaline.

From Sinhalese " turmali ". Group name for gems brought from Ceylon (Sri Lanka).

History of Dravite

Historically, this mineral was first found near the city of Dravograd, near the Drava River in the northern part of modern Slovenia. It is from this that the name of this material came. It was described in the scientific literature by the famous mineralogist from Austria Gustav T. von Seisnegg.

In the Russian Federation, this mineral is usually found in the Urals, in its middle part. The world's most beautiful version of this stone, dravite, which has a bluish-white hue, was discovered in the southern part of the Urals. In addition, stones are mined in Altai and Karelia.

In addition, this mineral can be found in its historical homeland in Slovenia, in the southern regions of Austria, Sri Lanka, Algeria and Kenya. China is famous for its green variety of stone, which also has the so-called “cat’s eye” effect.

The most impressive minerals in terms of size are mined in Australia, where a truly gigantic gold-colored dravite was found. Also, very large stones are supplied by Brazil, which is the undoubted leader in the number of tourmalines mined per year. The color of Brazilian stones is mainly brown.

These different, different, different stones

Tourmalines are distinguished by colors:

1. Chameleonite. Has an alexandrite effect. It is olive green in daylight and brownish red in artificial light.
2. Verdelite. Greens - from light spring greens to dark greens. The color is due to the presence of iron ions. The shades in the crystal change, smoothly shimmering.
3. Indigolite. Blue of all shades. The name comes from indigo, a shade of blue. In Russia in the old days it was called baus.
4. Dravit. Color ranges from pale cognac to rich brown. Named after the Austrian Dravet deposit.
5. Schorl. From the old German miner's term schorl. Black, gloomy, opaque. It is in great demand among magicians and sorcerers.
6. Sibirit. Purple-red stone. Found in Siberia, of course.
7. Achroite. It got its name from a combination of Greek words; means "without color". Rare colorless variety.
8. Liddicoatite. Relatively recently it was recognized as a separate variety of tourmaline. Geometric patterns can be amazingly beautiful.

Polychrome crystals are varied.

Some have a black or red top, called the "Moor's (Turk, Negro) head."

When cut, watermelon tourmaline can resemble a piece of watermelon, with a kelly rind and pink “pulp.” But there are also “stones in reverse” - the middle is green, surrounded by pink.

Physico-chemical

• The crystals are hard but brittle.
• Tourmaline that changes color when daylight changes to artificial light is called chameleonite.
• The crystals have a well-defined zonal growth pattern. The color change occurs not only along the main axis of the crystal, but also in the transverse direction.
• Dichroic; This is especially evident in the “head of a Negro (Moor, Turk)” variety.
• It has a piezoelectric effect (when pressed or mechanically applied, an electric charge appears on the surface of the crystal).
• Has pyroelectric properties.
• Mineral crystals are sensitive to temperature increases. If you electrify a crystal, its temperature changes. Tourmaline directly converts thermal energy into electrical energy.
• The red color of the gems is stable when heated.
• Red tourmaline has a strong pleochroism - from dark red to yellow to scarlet.

Questions/Answers

There are quite a lot of tourmalines. This article is a review, “about everyone in general.” But if you have questions, ask them.

How to distinguish a fake?

1. Examine the stone with a magnifying glass. A real gem has shimmers and halftones. The fakes don't have this.
2. Look for inclusions in the stone? A perfectly clean stone is most likely the work of human hands.
3. Natural tourmaline is difficult to scratch. This is not glass.
4. Rub the stone with a woolen cloth. Real tourmaline will attract hairs, tiny pieces of paper, and dust.

Please note: “watermelon” tourmalines are often made from cutting crystals of different colors.
In the 1920s, bluish tourmalines from Namibia entered the market. There was demand for green stones. Therefore, Namibian gems were heated, which changed their color to green.

Important : sometimes crystals are refined by annealing or irradiation. Such stones are not considered fake.

How to care?

1. Tourmalines are micro-vacuum cleaners. Therefore, store your jewelry in a tightly closed case.
2. If a pebble gets dirty, wash it in soapy water and rinse with clean water. Dry with a napkin. Try not to rub the stone. Otherwise, the piezo or pyroelectric effect will work, and your stone will find dust, like an exemplary housewife.
3. Gems do not like bright sun - they can fade. But even in the evening, under artificial light, tourmaline loses some of its shine and color.
4. Protect your jewelry from aggressive liquids and household chemicals.

How to wear?

• The gem will accept gold and silver equally well. Tourmaline will not accept simple frames (jewelry alloys, copper).
• The stone is rarely set in platinum.
• The magical properties of tourmaline are more pronounced in combination with silver.
• In the old days, tourmalines were recommended to be worn on the index finger of the right hand or on the middle finger of the left hand. Moreover, the frame should be gold or silver.

What is the price?

• A good option is to buy individual cut gems and give them to a jeweler to create a custom piece of jewelry.
• The differences between tourmaline varieties can be significant. Prices per carat of Paraiba start from $4000-6000. Connoisseurs will not be surprised by the price of $20,000 per carat.
• “Simple” tourmalines start at $20 per carat.
• But we must take into account that the price greatly depends on the variety.
• Weight, purity, color, variety affect the final cost of jewelry. And of course, add the cost of the frame here.

What colors are there?

Red, green, blue, black, tan and simply colorless.

There are more than fifty shades of tourmaline.

The most valuable ones are pink and red.

In second place are green ones, their color approaches emerald.

Polychrome types are good. One crystal can have up to five colors.

Where can I buy?

Large online stores, jewelry stores, exhibitions and sales of stones. Expensive varieties (for example, Paraiba) should be purchased where they will provide you with proof of the authenticity of the stone.

What stones does it go with?

For the most part, tourmalines are “selfish”. Their energy is self-sufficient; it can hardly tolerate the proximity of other gems.

Tourmaline especially conflicts with rubies, sapphires, and alexandrites.

Chemical and physical properties of stone

Dravite is a stone that belongs to the sodium-magnesium variety of tourmalines; its color directly depends on the impurities of which substance it contains. Typically, yellow stones are found in a light shade. This indicates an admixture of titanium. Much less common are admixtures of chromium, manganese, fluorine and calcium. The color is also different accordingly.

Due to the fact that it is only a form of a stone such as tourmaline, and therefore its chemical composition is similar, it can be called a complex ring silicate, having the following formula - NaMg3Al6[(OH)4|(BO3)3|Si6O18]. The luster of dravite varies from glassy to matte. May be transparent or translucent. Very low cleavage, virtually absent. Hardness on the scale: 7 - 7.5. Average specific gravity: 3g/cm3. The line is white.

In addition, this stone has the property of so-called pleochroism. In this regard, jewelers who process this stone need to determine the direction in which to cut. However, in general, jewelers rarely use this mineral. It is much more popular among collectors.
