Metrics and ring sizes

Piaget provides you with the opportunity to consult an online glossary as well as a conversion table of size charts for international ring sizing systems. This table shows the conversion between the various measurement systems, but may vary depending on the model and ring width. This information is given for indicative purposes only and in no way engages Piaget’s responsibility. Depending on the model, different measurements will be needed for the same finger.
