Is a Cheap Engagement or Wedding Ring a Divorce Omen?

I don’t think the price of the ring is dispositive but I do kinda think that the amount of effort and money a man invests in engaging a woman and marry a woman can say something about the level of commitment and regard for her. Even if he is poor, he should want to give her the very best he can afford to buy and if he cheapskates her when he can do better and gets her an ugly, cheap ring, that says a lot about his sentiments and yes, I think it could be a divorce omen.
Do you agree or disagree?
