The free ring sizer
Choose “Not sure — send sizer first” when ordering any ring. We ship a Korean ring sizer to you first, free of charge. Measure at home, send us your KOR number, and we craft your ring in that exact size.
Measure a ring you own
- Choose a ring that fits the finger you are sizing.
- Measure the inside of the ring at its widest point, straight across, in millimetres.
- Find the nearest inner diameter in the chart. Between two sizes, choose the larger.
