Helpful ring sizing tips

When you’re measuring ring size, don’t forget these useful tips.


Ensure not to measure your ring size when feeling cold, as this may result in a smaller measurement by half a size for your fingers.


Optimal for accuracy, measure your finger size in the evening, as it's when they typically reach their maximum size.


For the most accurate measurement, be sure to measure your finger at least three times to confirm the correct size.


Rings featuring wider bands tend to fit snugger, suggesting you might consider selecting a size larger than usual.

What if the ring doesn’t fit?

In the event that the ring doesn't fit perfectly, there's no need to worry. Getting the size spot-on can be a common challenge. If adjustments are needed, simply send the ring back for resizing to achieve that ideal fit.

We provide complimentary resizing within a range of 2 sizes up or down within 30 days after receiving the item. For resizing beyond two sizes, a fee of £69 will be applicable. The feasibility of resizing may vary based on the design complexity, and certain items might not be resizable.
