A UK ring size O has a circumference of 55.1mm, which means it's the equivalent to a US 7 and an EU 54 ⅝. It's a relatively common ring size, which means we typically have an extensive range of styles in this size. However, some of them are one-offs, so it's best to make a quick decision if there's a piece you love!

Because there are so many men's and women's rings in a size O to choose from, you should have no trouble finding a beautiful accessory to suit your needs. Whether you're planning to propose to your beloved and are shopping for an engagement ring in a size O, or you're looking to treat yourself to a size O diamond or gold ring, we'll have just the thing to fit the bill.

These aren't the only rings we stock, either. So, if you would like more options, make sure you check out our entire collection of luxury rings, as we often have pieces that can be resized to fit you perfectly.
