Tips for accurate sizing

  • Measure at the end of the day when fingers are warmest
  • Measure the specific finger you'll wear the ring on
  • Note that wider bands may need a half size up
  • If between sizes, go up for comfort

If you're unsure about your ring size, we recommend visiting a local jeweller for professional sizing or contact us for assistance.
