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.

1. Measure an Existing Ring
- Select a ring you have that you know fits your finger (or fits the other person's finger if you're buying a gift)
