The sizes in the website are US sizes. You can find your finger size by using the international size chart below and convert your size. This is for reference only. If you need help to find your best fit, we can help with any questions. Please contact us.
Bands
Band-style rings will mostly fit true to size. Choose your usual sizing that fits you most comfortably.
Cuff Rings
Cuff rings are designed with an opening and will run bigger in size. We recommend sizing down—0.5 to 1 US size smaller.
