October is one of the lucky months — it has two birthstones: the iridescent opal and the endlessly colourful tourmaline. Opal's real signature is its play-of-colour, a soft milky glow that flashes rainbow from within. This collection gathers our favourite opal- and tourmaline-inspired pieces — shimmering Moonstone and Labradorite that echo opal's fire, plus rose-and-pink stones that channel tourmaline — so every October baby (Libras and Scorpios alike) can wear their birth month, without the fine-jewellery price tag.
