Ring Size
Interior Diameter of the Ring in millimeters
GRB ring sizes correspond to the inside diameter of the ring in millimeters.
To find out what your size is, we suggest that you measure the inside diameter of your ring with a ruler.
Another alternative is to measure the circumference of your finger with a thread. Wrap it around your finger and cut it where the ends meet and then measure its length with a ruler.
If you already know your size, you can look for the equivalence.
