October birthdays come with an unusual advantage: there are two recognised birthstones to choose from. Opal is loved for its shifting flashes of colour, while tourmaline appears in an extraordinary range of shades, from soft pink to vivid green.
That variety makes October birthstone jewellery a thoughtful gift, but it can also make choosing the right piece more difficult. This UK guide explains the difference between opal and tourmaline, how to match each stone to the recipient, and how to care for the jewellery after gifting it.
What Are the October Birthstones?
Opal and tourmaline are both widely recognised as October birthstones. The Gemological Institute of America’s October birthstone guide describes opal as the traditional option and tourmaline as the newer alternative.
Although they share the same month, the two gemstones create very different looks. Opal is known for play-of-colour—flashes that may appear blue, green, pink, orange or yellow as the stone moves. Tourmaline is valued for its broad natural colour range and can offer a cleaner, more saturated appearance.
Opal vs Tourmaline: Quick Comparison
| Feature | Opal | Tourmaline |
|---|---|---|
| Appearance | Iridescent, with shifting flashes of colour | Available in pink, green, blue, black and multicolour varieties |
| Best for | Romantic, dreamy and individual gifts | Colourful, modern and versatile gifts |
| Everyday wear | Needs more careful handling | Generally more suitable for regular wear |
| Gift personality | Creative, sentimental or softly feminine | Confident, expressive or fashion-led |
Choose Opal for a Romantic, One-of-a-Kind Look
No two opals display colour in exactly the same way, which gives an opal-inspired necklace a personal quality. Pale opal tones work beautifully with gold-tone settings and soft colours such as ivory, blush and champagne.
Opal-style jewellery is a strong choice for a partner, best friend or family member who enjoys delicate pieces with an unusual glow. Pendants and earrings are especially gift-friendly because they are less exposed to knocks than rings.
Choose Tourmaline for Colour and Versatility
Tourmaline is one of the most colour-diverse gemstones. Pink tourmaline feels romantic and celebratory, green tourmaline has a fresh, modern character, and darker shades can create a more dramatic look.
For someone who wears jewellery frequently, a tourmaline-inspired pendant can be easier to coordinate with everyday outfits. Pink stones pair well with neutral knitwear, satin dresses and gold accessories, making them suitable for both birthdays and autumn celebrations.
How to Match the Necklace to Her Style
For a minimalist, choose a small pendant on a fine chain. For someone who loves romantic outfits, look for a teardrop, heart or floral setting. If she prefers statement jewellery, select a larger stone, layered chain or design with pearl-like accents.
Neckline matters too. A medium-length pendant is the safest gift because it works with crew-neck tops, open shirts and dresses. For more styling help, see our guide to matching necklaces with different necklines.
Make the Gift Feel More Personal
Presentation turns jewellery into a memorable birthday moment. Use a proper jewellery box, add a handwritten card and explain why you chose the stone. You could mention the recipient’s October birthday, her favourite colour or the meaning you associate with the design.

How to Care for October Birthstone Jewellery
Opal requires gentle care. The GIA advises using warm, soapy water and avoiding high heat or sudden temperature changes. Store opal jewellery separately so harder stones and metal edges do not scratch it.
Tourmaline is more durable, but it should still be protected from hard knocks and excessive heat. Clean it with warm, soapy water and a soft brush, then dry it with a lint-free cloth. Avoid harsh household chemicals on any gemstone jewellery.
Which October Birthstone Makes the Better Gift?
Choose opal when you want the gift to feel dreamy, distinctive and sentimental. Choose tourmaline when the recipient loves colour, wears jewellery regularly or prefers a more modern look.
The best choice is the one that reflects her personality. A thoughtful stone, a wearable necklace length and careful presentation will matter far more than following a single trend.
Final Thoughts
October birthstone jewellery offers twice the choice and twice the colour. Whether you select the soft, shifting glow of opal or the confident colour of tourmaline, the result can be a meaningful birthday gift she continues to wear long after October ends.
