Other ways to measure your ring size

Ask help from others

Asking your partner’s parents, or their best friends is
a great starting point. Get their friends and family to
casually try on some inexpensive rings in order to get
a rough idea of what the ring size might be.

Find the exact measurement

You can compare any of your measurements to our
international measurement table in order to find out
the right size. Simply download our PDF guide below.

What if the ring doesn’t fit?

Plenty of people don’t get the size right the first time. That is why we offer a 30-day free ring resizing service for up to 2 sizes up or down. For resizing more than 2 sizes either way, we charge 59€ for resizing/replacement. Please note that some designs such as full eternity rings, bespoke items, and engraved rings, cannot be resized. Contact our customer care team for more information on ring resizing - 0207 138 3672.

Any additional costs?

If there’s any additional resizing that needs to be done after our one-time 30 day period, then additional charges will apply. This can be as little as 59€ depending on the design, and delivery & insurance charges will apply in order to send the ring to us and back.
