Platinum Princess 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’.

When it comes to engagement rings, platinum has always been the most popular choice—accounting for over 60% of the rings we make today. Durable, naturally bright, and low maintenance, this precious metal makes platinum engagement rings last a lifetime. A platinum band with a unique ring is a match made in heaven, sure to make any centre diamond look its best for years to come.

For a engagement ring with an exciting presence, we recommend the princess cut diamond. A princess cut diamond is square in shape and comes with a stunning amount of sparkle despite its 90 degree angle corners. The brilliance of a princess diamond engagement ring comes from the diamond’s structure: on the underside of the princess cut, the diamond sides feature chevron cuts of usually two, three, or four facets that catch the light from any angle. Unique yet timeless, {{metal_type}} princess diamond engagement rings are some of our favourites.
