Wedding ring blues

My fiancé got me a ring and I hate it. I told him that I didn't like it but The problem is, I think it's customized and not sure if it can be returned. I'm really sad about it, because I told him what I wanted and something got lost in translation and now this ring he ordered is supposed to be delivered in February. Am I being a brat? Can anyone relate or have any advice?

****##UPDATE: so we talked about it, I gave it some thought and the only part I didn't like was the shape of the stone. So I told him just to have them change that part and I love the rest. He was really happy that I liked it. I feel bad that I felt that way at first but everything worked out. 😇
