Waterproof Gold Trillion Opal October Birthstone Necklace

A modern, minimal take on the classic opal birthstone necklace, designed with a tiny trillion-cut opal set into a clean geometric pendant.

The opal catches the light with flashes of green and blue, while its sharp triangular silhouette gives this October birthstone a contemporary feel. Rather than a traditional fine cable chain, we've paired it with a delicate 2mm x 3mm paperclip link chain, adding subtle texture without overpowering the petite stone.

Crafted from waterproof stainless steel with premium 18K gold PVD plating, the gold finish has been selected for its rich, bright tone – avoiding the flat or dull-looking gold sometimes associated with waterproof stainless-steel jewellery. PVD creates a durable bonded finish designed for excellent colour retention and everyday wear.

Delicate enough to wear solo as an everyday necklace, but especially lovely layered with shorter chains, pendant necklaces or other fine gold pieces.

Opal is the traditional October birthstone, making this a thoughtful October birthday gift, while its subtle colour and easy-to-wear proportions also make it a beautiful Christmas gift, bridesmaid present or self-gift.
