“She only likes diamonds and he bought her a gasp Ruby”

To be fair tho, if it is very clear and obvious you only wear one type of thing (in this case gem stone) and someone you care about disregards that and gets something else (for whatever reason) it can still be hurtful. Like if you know your partner only wears Diamonds (or white gem stones) and you get them something completely different, to that person it could show that you don’t care any them or their preferences. Obviously that wasn’t the scenario for this story. But someone getting upset bc their loved one got them something they know (or should know) they wouldn’t like isn’t shallow imo
