A woman receives an engagement ring, and it's huge, so much so that she has a major reaction to it. It shows that her fiance either makes some major money or otherwise is a major criminal. She may love it (possibly showing it off to everyone); a more down-to-earth character may think it's just too much to accept. Even if the character can't accept something so extravagant, she may take one last look at how beautiful it is before giving it back.
As what constitutes a "huge" ring is subjective, this is an in-universe trope. A character must react either verbally or physically to the size of it.
