Ring Size

How can I work out the ring size?

B) Compare your ring with the ring template.

Additional information:

The fingers of the left and right hands are usually slightly different sizes. Please bear this in mind when chosing which finger to measure. Most people find that the circumference of their fingers changes during the day; normally, the fingers are thicker in the evening than in the morning. Please bear this in mind when choosing your ring size so that you have a ring that fits well the whole day.

Don’t forget that, if your 21DIAMONDS ring doesn’t fit, we offer one free alteration as part of our service. If the ring is engraved however, we need to keep 50 Pounds. Simply contact our Customer Service team and send the ring back to us with your preferred measurement.
