Size Guide
To determine the size of your ring, please see the chart below.
The first column indicates our sizing, in US sizes, and the second column is the equivalent sizes in other sizing systems. The third and fourth columns indicate the millimetric measurements for each size.
In order to correctly choose your ring size, you can use a ring that you own and find the corresponding diameter on the ring (indicated in the fourth column).
In case of hesitation between two sizes, we advise you to choose the larger size, or visit a jeweler for assistance in measuring your ring size. You can always contact us at info@atelierorman.com.
