Ring Size Guide

This is a guide only and if you are unsure of your ring size, we would recommend visiting a local jewellers to be measured professionally.

Please be aware of the following:

  • Your finger size can change slightly throughout the day - the best time to measure is in the evening when your fingers are largest.
  • Avoid measuring when you are cold, as your fingers could be up to half a size smaller.
  • Rings with a wider band or stacking design will feel tighter than a narrower band.
  • The fingers on your dominant hand will likely be slightly bigger than on your other hand.
  • Your ring should fit comfortably and should be loose enough to slide over your knuckle, but not so loose it will fall off.
