Choosing a Platinum Engagement Ring

Platinum is naturally white, with a substantial feel that suits both minimal and intricate engagement-ring designs. Our platinum settings are made from a precious metal chosen for its lasting colour and everyday suitability. It does not rely on rhodium plating to achieve a white finish, although the surface can develop a softer patina through wear.

Compare the finish and weight in person

The difference between platinum and white gold is not simply one of colour. Platinum has a distinct density and surface character; white gold usually has a brighter rhodium-finished appearance that may require replating in time. Compare the two metals on the hand alongside the same stone shape and setting before deciding.

A high-set centre can feel very different from a lower-profile design, regardless of metal. Consider the width of the band and whether your chosen wedding ring will sit close to the engagement ring. For a focused choice of platinum with lab grown diamond centres, see our platinum lab diamond engagement rings.
