Determine your

ring size

It is best to visit our workshop to measure your ring size. If you are unable to come by, you can measure the diameter of a suitable ring (the inside and in mm). Make sure you do this on several points. The ring may be slightly deformed from wear. 


Don't have a suitable ring? Then you can measure your ring size with a piece of string:

  1. Cut a string of about 10 cm and put it around the finger. Cut it off where the string touches each other
  2. Measure the number of millimeters. That is your ring size. Keep in mind that the ring should go over the knuckle. Do not pull the string too tight.
