How to Measure

  1. You'll need either a measuring tape, piece of string, or strip of paper.
  2. Wrap it around your finger, right where you plan to wear your ring and mark the place where it joins.
  3. Lay your strip flat and use a ruler to measure the length up to the mark, all in millimeters.
  4. Refer to the circumference column in our chart above and match your measurement to the closest Éclat ring size.

  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.

  • 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.
