October Birthstones: Opal & Tourmaline Meaning
Share
October has two recognised birthstones: opal and tourmaline. One is admired for shifting flashes of colour; the other appears in an extraordinary range of shades. Together they give October birthdays more freedom to choose jewellery that reflects personal style as well as birth month.
What are the October birthstones?
Opal and tourmaline are the traditional modern choices for October. Opal is famous for play-of-colour, where rainbow-like flashes move across the stone as it turns. Tourmaline can be pink, green, blue, red, yellow or a combination of colours. Pink tourmaline is especially popular in October birthstone jewellery.

Opal meaning and symbolism
Opal has long been associated with hope, creativity and individuality. Its changing colours make it a natural symbol for a personality with many sides. These meanings come from cultural and jewellery traditions; they should be enjoyed as symbolism, not treated as claims about personal wellbeing.
Because every opal pattern looks slightly different, opal-inspired jewellery can feel especially personal. It suits someone who likes soft iridescence, unexpected colour and designs that change character in different light.
Tourmaline meaning and symbolism
Tourmaline is traditionally connected with affection, friendship and compassion. Pink tourmaline gives that symbolism a warm, romantic tone, while green or multicolour varieties feel lively and modern. Its broad colour palette makes it easy to choose a shade that genuinely matches the wearer.
Opal or tourmaline: which should you choose?
- Choose opal for luminous, dreamlike colour and a design that feels distinctive.
- Choose pink tourmaline for a soft, feminine accent with clear October symbolism.
- Choose multicolour tourmaline for a playful piece that works with several outfits and metals.
- Choose by lifestyle as well as appearance: opal needs more careful handling than tourmaline.
October birthstone jewellery gift ideas
An October stone can mark a birthday, an anniversary or a connection to someone born during the month. A small charm is easy to wear every day, while a bracelet adds visible colour without dominating an outfit. For a faith-inspired gift, explore the Cross Charm Birthstone Bracelet. For a more personal necklace, consider the Zodiac Birthstone Necklace.
Our birthstone jewellery collection brings together necklace, bracelet and charm options so you can compare styles before choosing.
How to style October birthstone colours
Opal’s shifting colours sit comfortably with both gold and silver tones. Pink tourmaline pairs beautifully with warm gold, cream, blush and burgundy, while green tourmaline works well with neutrals and earthy colours. If the jewellery is a gift, look at the metal the recipient already wears most often.
How to care for opal and tourmaline jewellery
Opal is relatively soft, measuring about 5 to 6.5 on the Mohs scale. Clean it gently with warm soapy water and avoid sudden temperature changes, prolonged heat, harsh chemicals, steam and ultrasonic cleaning. Store it separately from harder jewellery to help prevent scratches.
Tourmaline is more durable at about 7 to 7.5 on the Mohs scale, but it still deserves careful handling. Warm soapy water is generally the safest cleaning method. Avoid steam and ultrasonic cleaners, particularly when a stone may contain inclusions or treatments. Always follow the care instructions supplied with the finished piece.
Make October jewellery personal
The most meaningful choice is the one the wearer will reach for. Select opal for its unique movement of colour, tourmaline for its range of shades, or simply the October tone that best expresses the person you are celebrating.
