Our Tips

  • Temperature and time of day are important. Try not to measure your hands when they're too hot or too cold!
  • It's best to take your measurements in the evening when your hands are at their largest. If you find yourself between two ring sizes, always go with the larger one. 
  • If you (like a lot of us) have slightly larger knuckles than the base of your finger, you should go up half a size.
  • If you are purchasing a ring that has a wider band, we advise going one size up.

If you are still unsure, we suggest visiting your local jeweller.
