18k White & Yellow Gold Green Tourmaline Diamond Necklace

A slender rectangular green tourmaline gives this necklace by Louise O’Neill its distinctive silhouette. Framed in white gold, the gemstone sits beside a textured yellow gold disc and a small diamond, creating an asymmetric composition of clean lines, rounded form and delicate sparkle.

The elongated tourmaline introduces a rich stroke of green, its straight edges contrasting beautifully with the gold disc. The diamond adds a bright point of light beneath the disc, completing the arrangement without distracting from its simplicity.

This thoughtful balance of colour and proportion captures Louise’s approach to contemporary jewellery. Each element has its own character, while the combination feels cohesive: cool white gold, warm yellow gold and a vivid green centre of attention.

Wear it with an open neckline to highlight the pendant’s graphic shape, or let it bring colour to a simple everyday outfit. Its combination of gold colours makes it a versatile companion to jewellery in either metal—a distinctive, one-of-a-kind necklace for someone who appreciates the detail within a restrained design.
