Black tourmaline is usually schorl, the most common mineral in the tourmaline group, rich in iron; it is harder than glass (tourmalines have a hardness of 7–7.5 on the Mohs scale), so it withstands everyday wear. In tradition, it is regarded as one of the most powerful protective stones. Our jewelry featuring it starts at PLN 69; we most often sell the Protective Power bracelet for PLN 160 in silver or gold-plated silver, while among men's designs, the Raw Tourmaline bracelet for PLN 170. For display at home, we have raw schorl specimens from Brazil on steel stands.

Black tourmaline designs - from PLN 69
- What it is: usually schorl, the most common mineral in the tourmaline group. Its black color comes from iron, and raw crystals have elongated grooves.
- Will it withstand everyday wear: yes, it is harder than glass. It is less resistant to impacts against hard edges, while in elastic bracelets, the elastic itself wears out fastest.
- Meaning: in tradition, it is regarded as a protective and “grounding” stone; this is a belief not confirmed by medicine. According to GIA, tourmaline is also, alongside opal, an October birthstone.
- How much it costs: our jewelry costs PLN 69–369, and in most models, silver and gold-plated silver are the same price; specimens on stands are individual pieces, each with its own price shown on the product page.
What is black tourmaline?
Tourmaline is the name of an entire group of minerals: borosilicates with the same crystal structure and varying compositions. Black tourmaline is mostly schorl (German: Schorl), a sodium-iron tourmaline; the rarer dravite, a sodium-magnesium tourmaline, can also be black. The same family includes pink, green, blue, and multicolored stones, described in the guide to tourmaline varieties.
Its color comes from the large amount of iron in its composition; it also contains sodium, aluminum, boron, and silicon. In specimens and jewelry, it is almost opaque, with a vitreous luster, and its black color may have a brownish or bluish tint (the Mindat database contains complete data on schorl).
The history and origin of schorl
Before 1400, present-day Zschorlau in Saxony was called Schorl. Cassiterite, a tin ore, was mined in a nearby mine, and black tourmaline was found along with it. The first description of the mineral under the name “schürl,” from the tin mines of the Ore Mountains, was recorded in 1562 by Johannes Mathesius in the book “Sarepta oder Bergpostill”. The origin of the word itself is not known for certain; it may have referred to impurities.
Schorl forms in granites and granitic pegmatites, in hot hydrothermal veins, and in some metamorphic rocks. It occurs in many places around the world, but attractive crystals come from only a few locations, including Minas Gerais in Brazil, Namibia, and Afghanistan. The crystals are elongated prisms with a rounded, triangular cross-section, covered with grooves along their long axis. These grooves are the easiest way to identify raw tourmaline.

Black tourmaline — physical and energetic properties
On the Mohs scale, tourmaline has a hardness of 7–7.5, according to GIA. It is therefore harder than glass (5.5) and at least as hard as quartz (7), so the small beads in a bracelet are rarely scratched. However, it is brittle: a hard knock against the edge of a countertop can chip a bead.
Schorl is also heavier than it looks. Its density is 3.18–3.22 g/cm³, while ordinary window glass has a density of about 2.5 g/cm³.
When heated or compressed, tourmaline charges at opposite ends of the crystal and then attracts light particles of dust and ash; physicists say that it is pyroelectric and piezoelectric. This effect is not noticeable in small beads worn on the wrist.
In 1703, the Dutch brought from Ceylon a stone called tourmaline that, when heated, attracted ash from glowing coals as a magnet attracts iron, and then repelled it. Johann Georg Schmidt cited this account in 1707. They were referring to tourmalines from present-day Sri Lanka, but schorl has the same property. Linnaeus later named tourmaline lapis electricus, meaning “electric stone.”
The meaning of black tourmaline: grounding and protection
According to beliefs cited by GIA in its description of the October birthstones, black tourmaline protects the person wearing it and boosts their self-confidence. People who work with stones associate it with the root chakra (muladhara), which they believe is responsible for a sense of stability and security, hence the term “grounding.” This belongs to the realm of beliefs, not medicine: no stone can heal.
Does black tourmaline have any contraindications?
The stone itself does not, because it is neither a medicine nor a medical device. Lists of “contraindications” circulating online come from lithotherapy traditions.
When it comes to allergies, the setting metal matters. We make most jewelry containing metal from 925 silver or gold-plated silver. According to the workshop, our 925 silver contains no nickel, and we gold-plate it without an intermediate nickel layer.
The Tourmaline Stud Earrings and ring-style rings have gold-plated brass settings; we have no data on nickel in this metal. The Black Tourmaline Pendant has a gold-plated silver setting, while for the chain we currently state only that it is gold-plated. If you have a nickel allergy, choose a model in which all metal elements are made of 925 silver or gold-plated silver.
Put on an elastic bracelet without stretching it excessively, and take it off before bathing, swimming, or using a sauna: chlorine and soap weaken the elastic most quickly.
Can you sleep wearing black tourmaline and wear it every day?
You can wear it every day, but it is better to take the bracelet off before sleeping. The stone itself is hard, but the beads are held together by elastic, cord, or a chain, and these wear out faster than tourmaline. At night, the bracelet catches on the bedding and stretches the elastic; in our experience, this is the most common cause of breakage.
We also take it off for exercise and cleaning. You can wash tourmaline with soapy water, but detergents are harsh on the elastic, while perfumes dull the metal elements. What can harm it, however, are sudden temperature changes: thermal shock can cause it to crack, and high temperatures can change its color.
For everyday wear, the easiest option is a model with a clasp, such as Siła Ochrony for PLN 160: the extender lets you adjust the circumference, and nothing gets stretched when you put it on. We describe safe washing in our guide to cleaning stone jewelry.
How to identify genuine black tourmaline?
Raw schorl has longitudinal grooves along the crystal, is almost opaque, and has a glassy luster. It is also heavier than an imitation made from ordinary glass of the same size. Small cracks and surface irregularities are typical of natural stone.
The grooves are not visible on faceted beads, and only a gemological examination can provide certainty. A suspiciously low price for a large, perfect crystal is a warning sign. We have collected more ways to identify it in our guide to how to identify a genuine stone.
Are black tourmaline and onyx the same thing?
No. Black tourmaline is usually schorl, a separate mineral from the tourmaline group. Onyx is a variety of agate, meaning chalcedony, a fine-grained form of quartz.
According to GIA, what many people call black onyx is dyed chalcedony, because naturally black chalcedony is rare. The onyx in our jewelry is also dyed agate; learn more about it in the article on black agate.
| Stone | What it is | How to identify it | Mohs hardness |
|---|---|---|---|
| Black tourmaline (schorl) | iron-bearing borosilicate | longitudinal grooves on the crystals, glassy luster, almost opaque | 7 (tourmalines overall: 7–7.5) |
| Black onyx | chalcedony (agate), usually dyed | uniform, deep black color, smooth surface after polishing | 6,5–7 |
| Obsidian | natural volcanic glass | conchoidal fracture with sharp edges, glassy luster | 5–6 |
| Hematite | iron oxide | metallic luster, noticeably heavy (approx. 5.3 g/cm³), red streak on unglazed porcelain | 5,5–6,5 |
Black Tourmaline - Which Zodiac Sign Is It For?
Astrology most often associates black tourmaline with Scorpio and Capricorn. Its connection with Libra is October: most of this month falls under Libra, and according to GIA, October has two birthstones, opal and tourmaline. Tourmaline is better suited to a bracelet worn every day because opal has a Mohs hardness of only 5–6.5.
We have collected the stones attributed to the other signs in our guide to natural stones for the zodiac signs.
Black tourmaline in jewelry
Small 3 mm faceted beads are used in the Siła Ochrony bracelet, the elasticated ring, and the Moc i Styl necklace; the cut, meaning many small flat facets, gives them their sparkle. We thread larger beads, about 6 mm, onto elastic, also combining them with hematite and rock crystal. Raw pieces with grooves are used in some men’s jewelry, stud earrings, and a pendant in a gold-plated silver setting.
In the last 12 months, the best-selling items in our store were the Protection Strength bracelet (15 pieces), the Men's Raw Tourmaline Bracelet (14), and the Black Tourmaline Bracelet with an elastic band (12). Since 2018, we have sold approximately 600 pieces of jewelry and specimens with black tourmaline online, with sales peaking in December. Bracelets with other varieties of tourmaline are available in the tourmaline bracelet collection.

What to pair with black tourmaline?
In our designs, we combine it with hematite, rock crystal, and pyrite, because each stands out against the black. The Matte Black Tourmaline and Hematite Bracelet pairs matte tourmaline with shiny hematite, while the Black Tourmaline and Rock Crystal Bracelet combines black with transparent crystal. The Black Tourmaline and Pyrite Ring and the slim Pyrite and Black Tourmaline Bracelet on a clasp feature pyrite’s golden shimmer.
Keep different bracelets in separate pouches. Schorl is harder than, among other things, opal and obsidian, so it can scratch them when left loose in the same jewelry box. The rules against combining stones come from tradition, and every author gives different advice.
How to wear and style schorl?
925 silver looks cool and graphic with black, while gilded silver creates a warm contrast. The choice mainly depends on which metal you wear every day, because the bracelet should match your watch and wedding ring. Gilding wears off over time, so we clean gilded silver only with a soft, slightly damp cloth and dry it immediately.
Small 3 mm beads wear like a thin chain and are easy to combine with another bracelet. Larger beads and chunks look better worn alone or in a set kept in one dark color palette. The Moc i Styl necklace sits close to the neck, while the pendant with a raw crystal on a longer chain lies on a sweater: on black, mainly the gilded setting is visible; on a light color, the entire shape of the stone stands out. You can see the other jewelry varieties in the tourmaline jewelry collection.
Which hand should you wear black tourmaline on?
On the hand you use less, which for right-handed people is usually the left. The beads are then less likely to hit the desk, door handles, and the edge of your laptop. Wear your watch on the other hand so the case does not rub against the stones.
Traditionally, the left hand is considered to “receive,” while the right hand “gives back,” which is why protective stones are usually worn on the left. Even stone guides add that you can wear the bracelet wherever it feels more comfortable.
Sizes S, M, and L indicate the wrist circumference for which we make the bracelet. Women’s elastic bracelets have S 13–14, M 15–16, and L 17–18 cm; men’s bracelets have S 16–17, M 17–18, and L 18–20 cm.
Measure your wrist with a tape measure or a piece of thread. If the result falls between two sizes, our guide to choosing bracelet size explains which one to choose and how much extra room to allow. For bracelets with a clasp, a 3–4 cm extension chain lets you adjust the circumference without taking an exact measurement.

Black tourmaline for men
We make men’s styles with larger stones: 6–8 mm beads, matte pieces, and unpolished crystals, on elastic or cord, without metal. Black goes well with a shirt, sweatshirt, and steel watch. Before buying a December gift, measure his wrist circumference with a piece of thread: the elastic can accommodate half a centimeter of measurement error.
More styles are available in the men’s jewelry collection, and we write about styling in our guide to wearing black tourmaline every day.
Where should you place black tourmaline at home?
Lithotherapy enthusiasts place it by the front door to “guard” the threshold, or by their desk. Our specimens are raw schorl crystals from Brazil on steel stands; according to the product cards, they weigh between 1.7 and 2.2 kg, so place them on a stable chest of drawers, shelf, or desk, away from the edge.
A raw 300 g piece for PLN 180 is also enough for a desk. Specimens on stands, each one unique, are available in the black tourmaline collection. Remove dust with a dry, soft brush, which reaches between the ridges better than a cloth.
FAQ — frequently asked questions about black tourmaline
What makes black tourmaline stand out?
Its deep black color comes from iron, it has ridges along the crystal, and it becomes electrically charged when heated or compressed. According to popular beliefs, it protects the person wearing it.
How do you cleanse and care for black tourmaline?
Wash the stone itself with warm soapy water and a soft brush, without using an ultrasonic or steam cleaner. Do not soak elastic-band jewelry completely: wipe the beads with a damp cloth, then a dry one, and apply perfume and cream before putting it on. “Cleansing” it of energy is a lithotherapy practice: its followers briefly rinse the stone under cool water, expose it to sage or palo santo smoke, or leave it overnight in moonlight.
How Much Does Black Tourmaline Cost?
In our store, black tourmaline jewelry costs from 69 to 369 zł. The least expensive item is the elastic-band ring, while the most expensive is the bracelet and necklace set. A rough piece costs 180 zł, while specimens on stands are individual items, each with its own price on the product page. More designs are available in the black tourmaline collection.
Black Tourmaline - Which Zodiac Sign Is It For?
In astrology, it is most often associated with Scorpio and Capricorn, and as an October birthstone, also with those born in that month, mainly Libras. Anyone can wear it, regardless of their sign.
How Does Black Tourmaline Differ from Watermelon Tourmaline?
Both belong to the tourmaline group, but they have different compositions and appearances. Black tourmaline is usually schorl, rich in iron. Watermelon tourmaline is green on the outside and pink in the center, like a sliced watermelon. Beliefs associate black tourmaline with protection, and pink varieties, such as pink tourmaline, with matters of the heart.
