My best friend's boyfriend recently sought me out to help him find the perfect engagement ring for my best friend. He's got an idea of what ring she would like but wanted to double check with me before he made such a huge investment. Since she and I have been friends for such a long time, engagement rings have come up in conversation many times before and I know exactly the style that she would love. The only problem is I feel sort of helpless when it comes to finding a "quality" diamond. And her boyfriend is pretty much just as helpless. He knows that he's going to have to spend the money if he wants a nice ring, he just doesn't want to end up paying thousands for a piece of junk. I've heard about the 4 C's but am embarrassed to say that I'm clueless.
Can anyone point me in the direction for "Engagement Rings for Dummies"? Or just give me a few tips so I don't look foolish when he asks me to go with him and help him out. THANKS.
