Ring Size Guide
Find your fit before choosing your Eterna ring. VIVENZO uses US ring sizes. The Eterna ring and the ring included in the Eterna & Eteria Set are available in sizes 6 and 7.
Size reference
| US size | Inside diameter | Inside circumference |
|---|---|---|
| 6 | 16.5 mm | 51.9 mm |
| 7 | 17.3 mm | 54.4 mm |
These are approximate standard conversions, not measurements of each individual ring. Fit can vary with the ring's shape and width.
Measure a ring you already wear
- Choose a ring that fits comfortably on the finger where you plan to wear Eterna.
- Place it flat beside a millimetre ruler.
- Measure straight across the centre, from one inside edge to the other. Do not include the metal band.
- Compare the inside diameter with the table above.
For a more precise fit
A jeweller or a physical ring sizer can help confirm your US size. Measure when your hands are at their usual temperature. Your ring should feel secure while still passing comfortably over your knuckle.
