Still can't stop looking at it!

Cannot get over my Aria engagement ring. Many months before the proposal, my now-fiance and I went to the La Jolla showroom together to get an idea of what I liked and my ring size. I ended up picking my top 3 settings and choosing my ideal ranges for each of the 4 C's and left the rest up to him (still wanted it to be a surprise/his choice but with options I was guaranteed to love :) highly recommend doing this, ladies!). He went to the DC showroom a few months later with his mom to make the final decision and he said his experience was great with the consultants at both stores. The ring still looks and feels amazing 3 months in and I'm already excited to go back and pick out a wedding band!
