Here I have to tell you might think at first: just for the professional ... but if you need a very special gift and the friend may not know what it is about, it is trying so times). For me it worked and my friend knew to last from anything :) it was totally surprised! At night when the lady sleeping too cautious start with the largest ring gauge measure and slowly rantrauen to the appropriate ring size. Watching the the lady of your heart is asleep deep ... yes you should be able to assess after a while;) you see but otherwise even if the eyes move with closed eyelids). (Not easy, I understand in a dark bedroom) After you have your ring size but perfect and can be sure that it is not of an old ring is the nciht eh longer fits well, and can you also always give a ring for what;).
