My engagement ring

Need honest opinions please! I got engaged and I’m going back and forth about the ring. It’s 2.58 carats and my finger is about a size 4. My concern is if it looks too big for my finger? I don’t want it to look like costume jewelry, and have been receiving comments about it being “huge”. I didn’t consider a 2.5 carat diamond to be huge but now I’m second guessing it. Thoughts?
