Jewlery Care

Method 1: The String or Paper Strip Method

  1. Take a thin strip of paper or a piece of string
  2. Wrap it around the base of the finger where you plan to wear the ring
  3. Mark the point where the ends meet
  4. Measure the length from the starting point to the mark using a ruler (in millimetres for best accuracy)
  5. Compare the measurement with our ring size chart to find your correct size (in US sizing)
