SIZING GUIDE

If you wish to offer a gift to a loved one or simply want to know your size, we are at your convenience to assist.  

We invite you to choose a ring, measure its inner diameter and then choose the closest measurement on the table below, in order to identify your ring size.

If you are unsure and hesitate between two sizes, choose the largest. Please note that the style of the ring can also affect the choice of size: a larger ring should be worn loosely than a smaller ring.
