There isn't just one tourmaline. There are dozens: ink black, raspberry pink, bottle green, midnight blue, and sometimes several colors in a single crystal, like a slice of watermelon. Tourmaline is the stone of every color, and one of the richest in stories. It's the October birthstone and a favorite in tourmaline jewelry, especially in its black form. Here's a look at its geology, the origin of its name, its history, its meaning and properties, and how to wear it and care for it.
What is tourmaline?
Tourmaline isn't a single stone. It's a family of boron silicates that share the same structure and vary with the metals they contain. Mineralogists count around thirty species, but three names matter most in jewelry: schorl, rich in iron, which gives black tourmaline; elbaite, behind almost all colored tourmalines; and dravite, brown to yellow. Each color has its own variety name: pink to red rubellite, green verdelite, blue indicolite, and watermelon tourmaline, pink in the center and green at the edge.
It rates 7 to 7.5 on the Mohs scale, so it's a tough stone that's easy to wear every day. It grows in long prisms with a rounded triangular cross-section and lengthwise striations, which makes rough crystals easy to recognize. Brazil, especially the state of Minas Gerais, is the top producer. Afghanistan, Pakistan, Nigeria, Mozambique, Madagascar, Sri Lanka and the United States also have notable deposits.
Where does the name tourmaline come from?
The name comes from the Sinhalese turmali or toramalli, a word Sri Lankan gem traders used for mixed-color stones, without telling them apart. It fits: tourmaline was mistaken for other gems for a long time. Many "rubies" and "emeralds" in old treasuries turned out to be tourmalines, including some of the Russian crown jewels.
Tourmaline history and fun facts
Tourmaline has a physical quirk that fascinated 18th-century scientists: heat it or rub it, and it builds up an electric charge that attracts dust and ash. The story goes that Dutch merchants who imported it from Ceylon used it to clean their pipes, which earned it the nickname aschentrekker, or "ash puller." This effect, called pyroelectricity, is well understood today and gives tourmaline technical uses, in some pressure sensors for example.
Its big moment in fine jewelry came in the late 19th century, when pink tourmalines from California won over the imperial court of China, which had them carved into buttons, snuff bottles and jewelry. Since then, Brazilian deposits with electric colors have made it one of the most sought-after colored gems.
Tourmaline meaning and symbolism
Since tourmaline comes in every color, its meaning follows its shade. Black tourmaline is the stone of protection and grounding, a shield you wear. Pink is the stone of the heart and tenderness. Green stands for renewal and vitality, blue for communication and serenity. Watermelon, pink and green, brings the heart and its balance together. In the chakra system, each color has its center: root for black, heart for pink and green, throat for blue.
Tourmaline is one of the October birthstones, along with opal, and it's often called a stone for Libra. You'll find it in our jewelry for Libra.
Tourmaline properties in crystal lore
In crystal lore, black tourmaline is the go-to stone for protection. Keep it close to hold off the energy you'd rather leave at the door, and to stay grounded when everything around you is hectic. We wrote a full guide on it: everything you need to know about black tourmaline.
Each colored tourmaline has its own role. Pink is said to comfort the heart and invite gentleness, green to support drive and confidence, and blue to bring calm and thoughtful speech. Multicolored tourmaline, which brings them all together in one piece, is often chosen as a stone of balance. These meanings are symbolic: tourmaline doesn't promise anything, it simply keeps you company. You'll find it in our protection collection and among our pieces for balance and harmony.
Black tourmaline is known as a shield, and its colorful cousins as so many shades of the heart and of balance.
How to wear tourmaline
Tourmaline is best worn against the skin. On the wrist, the black tourmaline bracelet is the protection classic, simple and bold. The multicolored tourmaline bracelet runs through every shade from pink to green. On your finger, the multicolored tourmaline clover ring makes a good luck charm. Close to the heart, the tourmaline, amethyst and labradorite mala necklace pairs it with two stones of intuition.

How to clean and care for tourmaline
Tourmaline is tough and low-maintenance. To clean it, rinse it under lukewarm water with a little mild soap, rub gently and dry it with a soft, lint-free cloth. Since it naturally attracts dust as it warms up, a quick wipe now and then brings back its shine. Avoid hard knocks and sudden temperature changes.
To restore its glow, set it in soft morning light or on a selenite plate, a classic in crystal lore. All our tips are in our guide on how to cleanse and care for your crystals.
