I once worked at a jewelry store and this couple wanted to get an engagement ring. He was from a simple family and she was from a very affluent family. She said straight up, "I'm not getting married for anything less than 2 carats!" He bought a 2 carat diamond but he came back in 6 months saying that even that wasn't enough for her. If this news happened back then I suppose her demand would have been, "I'm not getting married for anything less than a planet!"
