Due to a very unfortunate event with a jeweler, I no longer have my original engagement ring and wedding band. I was devastated and thought I wouldn't want anything else. After a long time passed, DH took me out several times to look for something new but I never found anything I liked. Looking back, I think my heart just wasn't into shopping for a new one yet. I just wanted my originals.
A couple of years later, we found a ring that I fell in love with only to find out it was way out of our budget. That ring set me on the right path though. So fast forward a couple of years after that, and I was finally ready to work on a new ring set. It took a lot of research and time, but I ended up with rings that I love and they make me smile each time I look at them.
So what I'm trying to say is, take your time and don't let anyone influence your decision. You'll know it's right when you see it or when the idea comes to you.
