answer:You know, I racked my brain worrying about this just 5 months ago (now happily married). What I came to realize is that it all doesn’t even matter! Here are two steps to ensure happiness for you and your S.O. 1) Have a friend or relative recommend a place to go, just so you know you can let your guard down and you won’t get ripped off. 2) Tell the jeweler your price range and seriously . . . just pick a nice ring that you think looks very beautiful and that you will be proud to see on your S.O.‘s finger. Once I realized that the “4 C’s” are probably just another marketing ploy to get people to buy into it, and to justify higher costs, I said “F*** it,” and I just asked to see 4 – 5 unset diamonds in the size and shape I wanted. Then, I picked the one I thought was most dazzling. It worked out, and I saved myself alot of potential stress and brain power not worrying about “The 4 C’s” As long as you and your spouse think it’s a pretty ring, and you know you didn’t get torn a new one on the price, it will be fine.
