I have told friends and family we are having the ring made. I am not a very sentimental person, and I also have a hard time keeping a secret. When I am excited about something, I can't keep my mouth shut. Because of what I wanted, I had to mention to people that we were shopping because I wanted to use my mom's diamond in my ring for sentimental reasons (she passed away 15 years ago). In addition, we asked around for jeweler recommendations, so many people knew we were shopping and have asked if we found anything. Since I am the worst liar/secret keeper in the world (my boyfriend always knows what his Christmas or birthday present is about a month in advance), I was honest with them and told them that we were having it made. I have even shown some people the CAD image, and I know he has done the same because it looked so fantastic we couldn't keep it to ourselves. I really don't feel like I have ruined the experience whatsoever (aside from already seeing the ring which was an accident/mistake). But then again, I am not very sentimental and neither is he. I would do what feels right to you. I was concerned about telling people, but came to the conclusion that it is my decision, my engagement, and I don't care if other people think it is weird or if they think I am ruining the surprise. But I also know that a lot of people would have been unhappy if it were them. Overall though, I have found most people pretty excited for me, and I truly believe that they will be just as excited when I actually get the ring on my finger, and that is something I have no idea about. I also had a friend who is getting married in a couple months and she picked out the ring with her fiance as well and was there when he put in on layaway. Since she was there, she was able to try it on and took a picture of it and sent it to me, and I am sure I am not the only one she sent it to. This was about 3 months before he actually proposed. It really just depends on what you want for your proposal, but either way, I am sure it will be very special.
