Find Your Perfect Size

1. Select Your Finger

Fingers on your left and right hands may differ in size. Please measure the specific finger where the ring will be worn.

2. Measure Circumference
Wrap a strip of paper or non-stretchy string around the base of your finger (or knuckle if it's larger). Mark the overlap, then measure the length in mm to get your size.
