HOW TO MEASURE YOUR RING SIZE?

Option 1 

Order our complimentary RING SIZER and follow the instructions below. 

Please make sure that your ring sizer fits comfortably, so that will not be too loose to fall off but easy enough to slide over your knuckle. 

Option 2 

Measure the width of a ring you are currently wearing from the correct finger or measure the circumference of your finger with a string. Find the nearest measurements on the chart below. If unsure between two sizes, we recommend going for the larger size.

Some tips
  • Do not measure your finger when the hands are too hot or too cold, they may have shrunk or swell up to a size.
  • Salty food or alcohol can make your hands swell so try not to measure your ring size the morning after a pleasant soiree.
