October doesn’t make you choose just one colour. ✨
Opal captivates with an ever-changing play-of-colour, while tourmaline offers one of the most diverse palettes in the gemstone world. From dreamy iridescence to vivid pinks, greens and blues, both gems make beautifully personal expressions of style.
Which October birthstone would you wear—opal or tourmaline?
