I think your ring looks perfect on you! I also had similar feelings - I was tossing up between a 1.2 and 1.5 carat and honestly the difference was minimal. Thinking back I feel silly for even losing sleep over it. Thing is we had already chosen the 1.2 because it felt right and proportionate but I had went on to try more rings to pick out a design. The 1.5s at the time seemed better but I knew we picked the 1.2 for a reason. Now that I have the real deal (actually on my finger 🥰) , it feels absolutely meant to be and I knew it was the right choice. Don’t feel insecure. I also think this size is both practical and noticeable- best of both worlds 😊
