October Birthstone: Tourmaline
From vivid pinks to deep greens, October’s birthstone is one of the most colourful gems in the world. Tourmaline has become a favourite for jewellery lovers who want something personal, unexpected and entirely their own.
October has two birthstones, but few gemstones capture the imagination quite like tourmaline.
Known for its extraordinary range of colours, tourmaline can appear in almost every shade imaginable - from soft blush pink and vibrant raspberry to rich forest green, electric blue and warm champagne tones. Some stones even display more than one colour within the same crystal, making every gem beautifully individual.
For those looking beyond traditional diamond jewellery, tourmaline offers something particularly special: colour with character.
What is tourmaline?
Tourmaline is a family of gemstones rather than a single mineral. Its colour variations are influenced by its chemical composition, which is why the gemstone occurs in such a remarkable spectrum of hues.
Pink, green, blue, yellow, red and watermelon tourmalines are among the most recognised varieties, with some particularly coveted stones displaying striking colour combinations.
Unlike diamonds, where much of the conversation centres around the four Cs, choosing a tourmaline is often much more intuitive. Colour is usually the first thing you fall in love with.
The exact shade, saturation and character of the stone can make a significant difference to its beauty and value.

Green Tourmaline
Green tourmaline ranges from fresh, lighter greens to rich forest and olive tones. Deeper shades can have a sophisticated, almost emerald-like presence.
Blue Tourmaline
Known as indicolite, blue tourmaline is prized for its beautiful blue-green tones, ranging from ocean blue to deeper, more saturated shades.
Watermelon Tourmaline
One of the most recognisable varieties, watermelon tourmaline naturally combines pink and green within the same crystal, creating an unmistakably distinctive gemstone.
What does tourmaline symbolise?
Tourmaline has long been associated with individuality, creativity and self-expression.
Different colours are also traditionally believed to carry their own meanings. Black tourmaline is associated with protection and self-confidence, pink tourmaline with love and compassion, and green tourmaline with courage, strength and stamina.
Tourmaline is also traditionally given to celebrate the eighth wedding anniversary, making it a meaningful choice for marking a milestone.
At Cassandra Mamone, we love coloured gemstones for exactly this reason: no two stones feel quite the same.
Tourmaline offers an incredible opportunity to create jewellery that feels personal, whether you're celebrating an October birthday, marking a milestone or simply looking for a gemstone outside the traditional diamond palette.
Our loose gemstones can be selected as the starting point for a bespoke piece, allowing the design to develop around the stone you fall in love with.
Whether you're drawn to a soft pink, rich green, vivid blue or something completely unexpected, tourmaline is a gemstone worth seeing in person.
