We use the standard US sizing guide for our numbered sizes (7, 8, 9 etc) for rings and (S,M,L) for bracelets.

G.K has two options to determine your size.

  • Take a string or strip of paper and wrap it around the base of the desired finger.  Mark the point where the end meets the string or paper.  Then measure the string or paper on a ruler in millimeters to the point where you marked it. Finally, convert millimeters to ring size in the size chart below.(*You can also apply this method to determine the size of your cuff bracelet.)
  • We also offer the Ring Sizer by itself so you can determine your size.
