How to calculate the rings' measures:

Measure your finger with a thread and then spread it over a ruler and get the circumference in centimeters.
After you have obtained the circumference of your finger, see the table below where we reported all measures with different parameters: Italian measure, iso (international) measure and girth.

For gold rings

The exclusive presence of stem spring allows each ring dress three sizes simultaneously. Compare your measurement to the corresponding (small, medium, large) in our guide measures below.
