I just recently found out that my girlfriend''s ring size is 5! I had my sister-in-law ask girlfriend what her size was! Proposal will be total surprise, so I could not get exact size! My question to all is, what size should I actually get? 5, 5.25, or 5.5! I recently purchased a 1.36 D VS2 RB from GOOD OLD GOLD and I am having it set in a MARK MORRELL FLAME! I could have never made my purcase and my decisions if not for PRICESCOPE! I THANK YOU ALL for your responses and for all your help!
