Ring Size Guide

We strongly recommend having your ring size measured by a jeweller as self-measurement can be very tricky – even the slightest inaccuracies in measurement can significantly impact your ring size. If you're unable to visit a jeweller, consider ordering a ring sizer for a more accurate measurement at home. Or, you can watch our video guide below under the tab "Measure your Finger". Please note that we cannot be held responsible for incorrect sizes chosen through self-measurement.

How to Measure

  1. Select a ring that already fits your finger well.
  2. Take a ruler and measure the largest inner diameter of your ring in milimeters.
  3. Refer to the inner diameter column in our chart above and match your measurement to the closest Éclat ring size.

You will need:
1 x rectangular paper strip
1 x ruler
1 x pen
1 x tape

  1. Using the pen, draw an arrow on the top of the paper strip.
    (This is to show the starting point of your finger measurement.)
  2. Take a piece of tape and tape it to the front end, where the arrow is.
  3. Holding the paper strip end with the arrow, paste it on the finger you want to measure.
  4. Curl the paper strip around your finger. Do not pull the paper strip too tightly. 
    (The paper strip should not be tight but it should sit nicely on your finger.)
  5. At the first overlap, use a pen to make a mark on the paper strip. 
    (The mark should be clear and straight.)
  6. Remove the paper strip from your finger.
  7. Using a ruler and pen, elongate the mark on the paper strip.
  8. Align the paper and tape with the ruler, with the arrow end starting at the '0' on the ruler. 
  9. You can now obtain your finger measurement. 
  10. Refer to the circumference column in our chart above and match your measurement to the closest Éclat ring size.

Tips:

  • Measure your finger at the end of the day.
  • Ensure your hands are at normal body temperature, as fingers shrink in the cold and expand in the heat.
  • Make sure that the chosen size leaves enough room for the ring to pass easily along the entire length of the finger.

  • Using a Ring Sizer provides you with an accurate measurement of your finger.  It eliminates guesswork, ensures a comfortable fit, and reduces the chances of needing resizing later.
