Egyptian legend maintains that during its formation, Tourmaline passed over a rainbow as it made its journey from the Earth’s center which led to it assuming the seven colors of the rainbow. Tourmaline is mined in a vast array of colors; the widest range of colors of any gemstone in the gem kingdom with virtually every color represented, including black, bi-colors and tri-colors.



TOURMALINE - The Philosopher's stone

The popularity surrounding the Tourmaline gemstone did not start recently. In ancient times, it was used as an ornamental stone. The Egyptians, Greeks, and Romans, were convinced of its protective power, so they wore it as a talisman. During this period, black tourmaline was also associated with magic and sorcery. Legends have it that the great magicians of the time invoked this gemstone to protect themselves from demons and evil entities evolving on Earth.

 A well-known philosopher, Theophrastus wrote his treatise “On Stones,” about lyncurium (tourmaline, most likely) and other minerals. Theophrastus’s bizarre beliefs hinted at the stone’s pyroelectric (static electricity) properties, as it attracted straw, ashes, and small pieces of wood. Because of its pyroelectric effect, alchemists considered it to be linked to the Philosopher;s stone. The stone's abilities were, however, more worldly accepted 2000 years later, in 1707 in a book by author, Johann Georg Schmidt (Curious Speculations During Sleepless Nights), citing the Tourmalines' magnetic properties. “The Turmale (Tourmaline) has the property of not only attracting the ashes from the warm or burning coals, as the magnet does iron but also repelling them again.”  This fascination led to many findings and a naturalist Carl von Linné was the first to relate the pyroelectric property of tourmaline to electricity; he called the mineral ‘lapis electricus’—meaning electric stone. 

The popularity of this colored stone continued to peak in the 17th century when Jewelers used it to adorn the crowns of Russian monarchs and in the 18th century, when Dutch merchants imported large quantities from Sri Lanka. They named it "asshentrekker", meaning "ash headband", because of its electrostatic properties. This natural stone was said to be beneficial to artists, writers, actors, and creators. And there we have it even today, still adorned by the indigenous tribes, famous artists, and world leaders.



IS TOURMALINE A PRECIOUS STONE?

Yes. Tourmaline is considered a precious and most sought-after stone. Its value stems from its rarity, versatility, beauty, and profound symbolic meanings.

Here's why Tourmaline is considered a precious gemstone.

  • Tourmaline Meaning
  • The name "tourmaline" comes from the Sinhalese word "turamali," which means "stone with mixed colors." This reflects one of its most unique characteristics: the ability to appear in nearly every color of the rainbow, from pink and red to green, blue, black, and even multicolored varieties. Some tourmalines exhibit multiple colors in a single crystal, such as the famous watermelon tourmaline, which features green and pink bands resembling the fruit.

  • Rarity and Global Sources
  • While tourmaline can be found in many regions worldwide, high-quality stones are rare. Some of the most notable sources include Brazil, Sri Lanka, Congo, Madagascar, Namibia, Mozambique, Tanzania, and most recently Kenya, where deposits yield some of the finest specimens.

  • Rare color variations, such as Paraíba tourmaline—a vivid neon blue-green variety—are exceptionally valuable. Mining of tourmalines is often done in challenging environments, and extracting high-quality stones requires expertise.

  • Healing and Metaphysical Properties
  • For centuries, tourmaline has been valued not only for its beauty but also for its healing and metaphysical properties. Different colors of tourmaline are believed to correspond to various aspects of emotional, spiritual, and physical healing. 

  • Durability and Practical Use in Jewelry
  • Tourmaline ranks between 7 and 7.5 on the Mohs hardness scale, making it relatively durable for everyday wear in various types of jewelry. Its durability, and vibrant colors, make it an excellent choice for engagement rings, earrings and bracelets. Read our Tourmaline Buying Guide for an in depth look at quality factors. 

  • Tourmaline Crystals
  • Tourmaline is a crystalline boron silicate mineral that occurs in a wide variety of colors, thanks to trace elements like iron, manganese, and lithium present during its formation. First discovered in the late 1600s by Dutch traders, Tourmaline is found in regions such as Brazil, Madagascar, the United States, Afghanistan, and parts of Africa, making it a globally distributed gemstone. The geological conditions required for its formation mean that each tourmaline deposit can yield different colors and qualities of crystals.

TOURMALINE'S UNIQUE FORMATION

Tourmaline is its own gem species, with many different unique types. It forms in an incredible prismatic crystal habit, meaning that it forms in gorgeous long hexagonal 'pencils' within the host rock.

Tourmaline has many remarkable qualities but one of the most interesting physical attributes is that it has the ability to become magnetic under heat or pressure. When heat is applied to Tourmaline and becomes magnetic, it's known scientifically as Pryoelectric. In fact, this was so effective e dutch used Tourmaline to "suck" ash from their meershaum pipes, by heating a Tourmaline crystal in a fire.  Similarly, applying pressure to Tourmaline achieves the same effect  and is called Piezoelectric.
