Ring Size Guide

Please note that ring sizes can vary across different regions and there are various sizing systems used worldwide. At Vault, we utilize the Hong Kong sizing system; however, there's no need to worry as we have the capability to convert sizes. If you inform us about the sizing system that was used to measure your ring size, we can easily perform the conversion.

Additionally, you can use our ring sizer to obtain a more accurate measurement.
