Size guide
+/-: Smaller or larger sizes available, to be confirmed. Contact us.
Regarding rings French sizes correspond to the inner circumference of the ring in millimeters.
An ideal size is one that allows the ring to pass the knuckle with light to moderate resistance.
If you are between two sizes, choose the more fitted one.
To determine a size precisely, there are two solutions:
1. Go to a jewelry store to have your size determined by a professional
2. Order a ring sizer to determine your measurements at home. Order our ring sizer by clicking here
We do not recommend any other tricks, such as wrapping a string around your finger, which is not precise.
If you want to give a surprise ring, follow our recommendations .
BRACELETS:
Please simply let us know your wrist size corresponding to the sizes offered as options.
