Size guide

How we measure our rings

Our jewellery sizes follow the French standard.
The fit of a ring varies according to its design. More or less as happens with clothing and footwear.
The fit refers to a ring's adaptability and closeness to the finger, and, regardless of size, can be defined as follows:

  • Standard: close to the finger's actual size. The size matches the measured size.
  • Tight: tends to resist when coming off. It may be necessary to size up.
  • Loose: leaves space between the finger and the ring, may be too loose. It may be necessary to size down.
