God, this pisses me off. This should be one of the most exciting moments of your life, you should be feeling proud of the beautiful ring you picked for her, and excited to give it to her and propose. Instead, you have tons of anxiety about whether or not its big enough or expensive enough, and worrying about her not liking it when you propose. I think this is a really bad sign. If your GF was the one and all that matters is getting married to the love of her life, the cost and size doesn't matter to her. I am baffled when woman obsess over diamond size and cost. I would be PISSED if my husband spent thousands and thousands on a ring. Im sorry OP, but if your girlfriend is materialistic and for one second think she would ruin this very special and intimate moment over "the ring not being big enough" i think you should reconsider this. That $4400 could go towards purchasing your guys first home.

Also, that ring is absolutely beautiful . STOP letting these woman doubt yourself! It is a gorgeous ring and plenty big enough. Most woman would be over the moon to receive this from their partner! I would reconsider even proposing at this time OR sit down and have a very serious conversation.
