I posted this on another thread and was told to just start a new one! So here it is - I didn't really want to have to help my boyfriend pick out my engagement ring (because I wanted a surprise) but he is terrified of doing the wrong thing so I'm helping him at least with research. It seems like you don't need to know that much - the 4Cs. What else should i know??? 4Cs, where to buy, what kind of papers the ring should have, etc. Thanks!!
