by mpk24 » Jul 23, 2019 I am looking for help in purchasing an engagement ring for my girlfriend. I have a general idea of what she is looking for, but not sure if it is best to go to jeweler or search on my own. My girlfriend has seen several rings that she loves on Ring Concierge. Can anyone lead me in the right direction of how to start the process? I am looking for a decent size diamond (4 carat?), so I am trying to be smart in purchasing it in order to get a good deal.
