It actually doesn't matter how she finds out that you lied to her about the biggest life change she will ever experience for the rest of her life. What matters is that lying to a person you want to marry is a sure-fire way to end the marriage at some definite future point.
Arguing that it's okay because you will never be found out isn't relevant.
I didn't argue this at all, and in a reply to another comment below, 3 hours before your comment, I made it clear that all I was saying was that it's a bit farfetched to say someone is going to be embarrassed in front of her friends because of the ring.
> I didn't argue this at all,
I apologise. In the bit that I quoted, specifically this sentence:
>>>> I would think the only way the wife would know is [...]
it appeared to me that you were arguing that the wife would never know unless [...] happened. To me, that sentence implies deceiving the wife.
I am a person who doesn't wish to spend $20,000 on a rock so that my wife won't be embarrassed in front of her friends. And that is why I chose to marry a woman who thinks that spending $20,000 on a rock is a silly thing to do.
That was my point. If you married someone who doesn't like diamonds, fine.
The original comment was about "shenanigans like buying something else and passing it off as a diamond". Isn't there anything your partner likes? Would you buy something else because you don't wish to spend $X on Y, "passing it off as Y", and embarrass her in front of her friends?
Same thing, just that's more convincing to some people/shows it's not 'cheaping out', it's just a better deal.
That's not the argument, AIUI. The argument is "Go ahead and spend $FOO on a rock, just be sure not to lie about how much you spent".
