18k White Gold Marquise Diamond Engagement Rings

We want the process of finding a ring to be a creative act, one that gets to the heart of what makes your love unique. Our collection of engagement rings features a diverse range of styles, metals, and ring shapes, making it easy for you to feel confident that you’ve found ‘the one’.

White gold engagement rings are second to none when it comes to classic romance. Refined and bright, engagement rings look their best set in white gold as this precious metal can bring light and detail to each handcrafted design feature. Ideal for intricate metal work such as milgrain and filigree, 18k white gold is perfect for the romantics at heart.

Marquise diamonds bring together the best of an elongated diamond shape and the brilliant facet structure of a round diamond. The result is a diamond that flatters on the finger and catches the light in a mesmerising way, especially when set in 18k white gold. Marquise diamond engagement rings are uncommon, but that’s what makes them so beautiful. Like the irreplaceable nature of your love, white gold hexagonal diamond engagement rings have the charm of feeling one of a kind.
