I went to the jeweler to finalize my wedding band tomorrow and FI is going and buying his/mine tomorrow. I'm super excited. Thanks for all the advice. In the end, I decided on going with the more expensive ring...and using my negotiating tactics to get them to lower the price. So excited!
It's funny, I ended up trying on more this time and was deciding between some different ones than I'd originally considered. I'm extremely happy with my choice.
I really appreciate those who gave advice and opinions in the previous post. It really gave me a lot to think about and consider.
