Versatile Tourmaline: October's Other Colorful Birthstone

Tourmaline is an incredibly versatile and captivating gemstone, prized for its remarkable variety of colors and unique bi-color or even tri-color variations. Unlike most gemstones, which are limited to a specific range of hues, tourmaline comes in nearly every color of the rainbow, including pink, green, blue, yellow, red, and black. This wide color spectrum, along with its ability to display multiple shades within a single stone, makes tourmaline especially popular for those who seek one-of-a-kind, customized jewelry pieces.


What is Tourmaline?

Tourmaline is a complex boron silicate mineral that comes in a variety of vibrant colors due to different trace elements. It is well-known for its ability to display multiple colors in a single crystal, which makes bi-colored and even tri-colored stones especially prized and highly valued. Tourmaline rates a 7-7.5 on the Mohs hardness scale, meaning it is durable enough for everyday wear but requires some care to avoid scratches.


Why Choose It for Your Custom Design?


  • Color Variety: Tourmaline offers a spectrum of colors—ranging from vivid pinks and greens to rich blues, yellows, and even black. Its multi-color properties make each stone one-of-a-kind.
  • Affordability: Compared to many other gemstones, tourmaline can offer excellent value, especially for those who love bold, colorful jewelry.
  • Symbolism and Meaning: Known as a stone of reconciliation, tourmaline is believed to foster compassion, love, and friendship, making it ideal for meaningful gifts or personal statements.
  • October & Zodiac: Libras are drawn to its balancing energy, which helps harmonize emotions and thoughts, promoting clarity and calmness. For Scorpios, tourmaline is thought to amplify their natural intuition and support emotional healing, making it easier to release negativity and embrace transformation.

What to Consider When Purchasing

  • Color: Tourmaline comes in every color of the rainbow, including shades of pink, green, blue (also called indicolite), and yellow. One of the most unique features of tourmaline is its bi-color or multi-color variations, such as watermelon tourmaline, which has a pink center and green outer rim. When choosing, consider the vibrancy and saturation of the color, as it significantly impacts the stone’s value.

    • Pink Tourmaline : Ranges from soft blush to vivid fuchsia, often symbolizing love and compassion.
    • Green Tourmaline : Found in shades from pale mint to deep forest green, it is highly sought after for its fresh, natural tones.
    • Blue Tourmaline (Indicolite) : A rarer variety, offering hues from light turquoise to rich navy, evocative of tranquility.
    • Red Tourmaline (Rubellite) : Deep, passionate reds that can rival the richness of rubies, perfect for those seeking a bold statement.
    • Yellow Tourmaline : This sunny, golden shade brings warmth and positivity to any design.
    • Black Tourmaline (Schorl) : Often used for protection and grounding, black tourmaline provides a dramatic, modern look.
    • Watermelon Tourmaline, is a bi-color stone that blends pink and green, resembling a slice of watermelon. This unique coloration makes it especially popular for playful, eye-catching designs.
    • Bi-Color & Tri-Color: Tourmaline can come in a blend of colors and varieties from yellows to blues or similar varieties of watermelon tourmaline.

  • Clarity: Like most gemstones, tourmaline can have inclusions, which are tiny imperfections inside the stone. While some inclusions are acceptable, too many may dull the brilliance. Clear, transparent tourmalines are more valuable, especially in larger carat sizes.

  • Cut: The cut of the tourmaline is vital for showcasing its natural beauty. Some cuts, like emerald or step-cut, emphasize its rich colors, while brilliant cuts maximize sparkle. For bi-color stones, specific cuts highlight the transition between hues.

  • Durability: With a Mohs hardness of 7-7.5, tourmaline is durable but can still scratch. Avoid heavy wear if using it in rings, especially those worn daily, such as engagement rings. Protective settings may help preserve the stone’s surface.

Interesting Facts

  • Mistaken Color: Tourmaline is often confused with other gemstones due to its variety of colors. In fact, the famous "Caesar’s Ruby" in the Russian Crown jewels is actually a red tourmaline, not a ruby.
  • Ancient Egypt: Tourmaline was believed to have traveled through a rainbow during its journey from the earth’s core, which explained its wide array of colors. This legend led to the nickname “gem of the rainbow.”
  • Ancient Beliefs: Many cultures believed tourmaline had mystical powers. It was said to protect against negative energies, deflecting evil and promoting healing. It was also thought to help wearers gain insight, making it popular with shamans and healers who used the stone for spiritual purposes.
  • Dutch Traders: In the 1700s, Dutch traders brought tourmaline from Sri Lanka to Europe, where it became popular among jewelers. They called it "ash puller" because heated tourmaline could attract and repel ash particles due to its pyroelectric properties, further adding to its mystical allure.

Our Recommendation for Tourmaline in Custom Jewelry Designs


  • Array of Color Choices: Tourmaline is a stunning choice for anyone who loves vibrant colors and unique stones. Its versatility makes it a perfect match for rings, earrings, and necklaces, especially when you want a stone with character and variety. We love watermelon tourmaline and similar variations of bi-color and tri-color in tourmaline colors because of their distinctive two-tone appeal—it makes a fun statement piece in pendants and cocktail rings.
  • Strength & Value: While tourmaline offers a beautiful range of colors, there are other, more durable gemstones with vibrant hues that may be better suited for your custom design that offer more strength and durability. 

Tourmaline offers a stunning array of colors, with many options at accessible price points, making it a versatile gemstone choice for any jewelry design.


If you love the color diversity of tourmaline but are looking for other options, consider sapphires for similar durability and color variety or amethyst for a bold purple hue at a lower price point. Both of these gemstones are suitable alternatives if tourmaline is out of your budget or not your preferred style.
