Tourmaline is a gemstone that belongs to a complex group of silicate minerals. It’s known for its incredible diversity of colors, which can range from deep blacks to bright pinks, vivid greens, and everything in between. The name “tourmaline” comes from the Sinhalese word “turamali,” meaning “stone with mixed colors.” This description aptly captures the essence of tourmaline, as it often exhibits more than one color within a single crystal, sometimes even displaying a spectrum of hues.
Tourmaline has been admired by cultures around the world for centuries. In ancient times, it was believed to have mystical properties, capable of protecting against negative energies and promoting healing. Today, it remains popular not only for its aesthetic appeal but also for its metaphysical attributes, making it a symbol of versatility, adaptability, and emotional balance.
The Formation and Properties of Tourmaline
Geological Origin
Tourmaline forms in a variety of geological environments, primarily in igneous rocks like granite pegmatites and in metamorphic rocks. The presence of different trace elements during its formation is what gives tourmaline its wide range of colors. For instance, iron-rich tourmalines tend to be black or bluish-black, while manganese can produce pink and red shades. Lithium, aluminum, and other elements contribute to the vibrant greens, blues, and yellows seen in certain tourmaline varieties.
Physical and Chemical Properties
Tourmaline is composed of complex borosilicate structures, which include various elements such as aluminum, boron, silicon, oxygen, and hydroxide. Depending on the specific composition, tourmaline can exhibit a hardness on the Mohs scale ranging from 7 to 7.5, making it relatively durable and suitable for jewelry. Its electrical properties are also noteworthy; tourmaline can become electrically charged when heated (pyroelectricity) or subjected to pressure (piezoelectricity).
Types of Tourmaline
Elbaite
Elbaite is the most common and colorful type of tourmaline. It includes the highly prized Paraíba tourmaline, which features an intense neon blue or green due to the presence of copper. Elbaite can display almost every color imaginable, including bi-color and tri-color stones that show distinct bands of different hues.
Dravite
Dravite is a magnesium-rich variety of tourmaline that typically appears brown or yellowish-brown. However, dravite can also occur in green and occasionally in dark green to black. Dravite is less common in jewelry but is appreciated by collectors for its unique coloration and rarity.
Schorl
Schorl is the most abundant form of tourmaline, accounting for about 95% of all tourmaline found in nature. It is predominantly black or dark gray and is often used in jewelry for its durability and striking appearance. Schorl is also valued in metaphysical practices for its grounding and protective properties.
Liddicoatite
Liddicoatite is a rare calcium lithium aluminum tourmaline that can display a wide array of colors in a single crystal, including pink, green, blue, and yellow. It is named after Richard T. Liddicoat, a renowned gemologist who made significant contributions to the field of gemology.
Uvite
Uvite is a calcium-magnesium tourmaline that can be found in various colors, including brown, green, and red. It is less commonly used in jewelry but is appreciated by collectors for its unique properties and beautiful color combinations.
Mixed Tourmalines: A Symphony of Colors
Bi-Color and Tri-Color Tourmalines
One of the most striking features of tourmaline is its ability to display multiple colors within a single crystal. Bi-color tourmalines feature two distinct colors, often separated by a clear boundary. Common bi-color combinations include pink and green, known as “watermelon tourmaline,” and blue and green, which can resemble the ocean. Tri-color tourmalines take this phenomenon a step further, showcasing three different colors in a single stone. These stones are highly prized for their rarity and visual appeal.
Watermelon Tourmaline
Watermelon tourmaline is perhaps the most famous example of a bi-color tourmaline. It gets its name from its resemblance to a slice of watermelon, with a pink core surrounded by a green outer layer. The pink color is caused by manganese, while the green is due to iron. Watermelon tourmaline is not only beautiful but also symbolic, representing the balance between love (pink) and growth (green). It is often associated with emotional healing and the cultivation of compassion.
Paraíba Tourmaline
Paraíba tourmaline is a rare and highly sought-after variety of elbaite that exhibits an electric blue or green color, thanks to the presence of copper. Discovered in the 1980s in the state of Paraíba, Brazil, this gemstone quickly gained international attention for its vibrant, neon-like hue. Paraíba tourmaline is not only a symbol of luxury and rarity but also represents inspiration and creativity. Its intense color is said to stimulate the mind and promote innovative thinking.
Rainbow Tourmaline
Rainbow tourmaline refers to a stone that displays a wide range of colors, often in a gradient or banding pattern. These stones can showcase hues of pink, green, blue, yellow, and even purple. Rainbow tourmaline is a powerful symbol of diversity and unity, representing the blending of different energies and perspectives. It is often associated with spiritual growth and the expansion of consciousness.
The Symbolism of Mixed Tourmalines

Mixed tourmalines are symbols of versatility and adaptability. Just as these stones can display multiple colors, they remind us of the importance of being flexible and open to change. In a world that is constantly evolving, mixed tourmalines encourage us to embrace new experiences and adapt to different situations with grace and resilience.
Emotional Balance and Healing
Tourmaline, in general, is known for its emotional balancing properties. It helps to harmonize the heart and mind, promoting a sense of calm and inner peace. Mixed tourmalines, with their diverse color palette, are particularly effective in addressing a wide range of emotional issues. For example, the pink and green combination in watermelon tourmaline can help to heal emotional wounds and foster self-love, while the blue and green hues in Paraíba tourmaline can promote clarity and mental focus.
Creativity and Inspiration
The vibrant colors of mixed tourmalines make them powerful symbols of creativity and inspiration. They encourage us to explore new ideas and express ourselves authentically.

Spiritual Growth and Enlightenment
In many spiritual traditions, mixed tourmalines are associated with spiritual growth and enlightenment. The blending of different colors within a single stone represents the integration of various aspects of the self, leading to greater self-awareness and personal transformation. Mixed tourmalines are believed to enhance intuition and connect us to higher realms of consciousness, guiding us on our spiritual journey.
Protection and Grounding
While tourmaline is often associated with emotional and spiritual healing, it is also a powerful protective stone. Black tourmaline, in particular, is known for its ability to shield against negative energies and promote a sense of safety and security. Mixed tourmalines, with their combination of colors, offer a balanced approach to protection, grounding us while also opening us up to positive energies and opportunities.
Mixed Tourmalines in Jewelry Design

The versatility of mixed tourmalines allows for endless combinations, making them a favorite among designers and collectors alike.
Ethical and Sustainable Sourcing
As consumers become increasingly conscious of the environmental and social impact of their purchases, the demand for ethically sourced gemstones has grown.

Many jewelers now prioritize working with suppliers who adhere to ethical mining practices, ensuring that the gems they use are conflict-free and environmentally friendly. This commitment to sustainability adds another layer of meaning to mixed tourmaline jewelry, making it a thoughtful and responsible choice for those who value both beauty and ethics.
Caring for Mixed Tourmaline Jewelry
Cleaning and Maintenance
To keep your mixed tourmaline jewelry looking its best, it’s important to follow proper cleaning and maintenance guidelines. Tourmaline is relatively durable, but it can be sensitive to harsh chemicals and extreme temperatures. It’s recommended to clean your tourmaline jewelry with a soft cloth and mild soap and water. Avoid using ultrasonic cleaners or steam cleaners, as these can damage the stone. Additionally, store your tourmaline jewelry separately from other pieces to prevent scratches or chipping.
Handling and Wearing
When wearing mixed tourmaline jewelry, it’s important to handle it with care. While tourmaline is relatively hard, it can still be prone to chipping or cracking if exposed to excessive force. Avoid wearing your tourmaline jewelry during activities that involve heavy lifting or physical exertion. If you notice any signs of wear or damage, take your jewelry to a professional jeweler for inspection and repair.
