Let's help you get the perfect fit

We have 3 easy ways to help you know the right ring size for you, or the right ring size for someone you would like to surprise. Rosea Luna rings follow the US & Canada ring sizes. If you know your ring size according to different sizing standards, please use the Ring Sizing Chart below to locate your US & Canada size.

Measure Your Finger - Ring Sizing Guide - Rosea Luna

- Use a piece of paper to wrap around your finger and mark the place where the two sides meet. 

- Place the paper flat on a surface and measure the distance (in mm) between the marks to know the circumference of your finger. 

- Use the Ring Sizing Chart to find your US & Canada ring size.
