Getting the absolute right ring size is easiest if you have the cooperation of the recipient. Don't forget we are also here to resize your ring if you don't have the help of the receiver. Honestly the best way to find out the correct size is to go to the mall jewelers or a dept. store such as JC Penney, Sears, Walmart etc. these stores all have a jewelry center from which you can ask to have your finger sized with a professional ring gauge to see what you need in a ring size. If you simply guess the size or use other non professional methods the finger it goes on might suffer symptoms of irritation needlessly, but we are always here to help.
