Tips for Accurate Sizing

  • • Measure at the end of the day when fingers are slightly larger
  • • Avoid measuring when hands are cold (fingers shrink)
  • • Measure the specific finger the ring will be worn on
  • • If between sizes, round up for wider bands and down for thin bands
  • • Not sure? We offer free resizing on all engagement rings
