RING SIZE GUIDE

To help you choose the right ring size, we suggest referring to our Size Guide.

Each circle corresponds to the inside diameter of the ring. The letter in the middle is your size in the U.K. To determine the size of your ring, you can measure the inside diameter of your ring and find the corresponding measurement in our guide. Alternatively, put your ring on the printed chart to compare and find the best fit. The 10cm line guide will help to make the best judgment on the accuracy of the printed sheet. If in doubt of which size to choose, we advise you to choose the larger size.

Please refer to our International Ring Size Chart for a worldwide ring size comparison. Additionally, do not hesitate to Contact Us for any further assistance.

 

Once you have located the correct ring size, you can then choose your perfect ring from our site with the reassurance of the right fit.

Please bear in mind that this is a guide only and it does not provide 100% accuracy. We recommend you to measure ring size at your local jeweller’s, as this will guarantee the most precise measurement.
