How this brand sizing works

Cartier points shoppers to finger circumference in millimetres and recommends choosing the larger size when hesitating between two sizes.

The Love ring is a rigid band with a substantial profile. If EU 52 feels close but tight at the knuckle, compare EU 53/54 before ordering.
