SIZE GUIDE

How to measure your ring size:

1. Select a ring that fits the finger you plan to wear it on.
2. Place the ring on a flat surface.
3. Using a ruler, measure the inside diameter of the ring from one side to the other, in millimeters.
4. Compare your measurement with our size guide to find your ring size.
   
   

For example, if the diameter measures 18mm, the closest match would be a size 8.
