Use a ring you already have
Perfect if you already have a ring that fits you well.
1. Choose a ring that fits comfortably on the finger where you will wear your Tuna jewelry (not too loose or too tight).
2. Measure the inner diameter of the ring (from inner edge to inner edge) in millimeters.
3. Consult the size chart and find the corresponding size. If you are between sizes, choose the larger size.
