Interesting read and great points. But the reason I'm shopping for a diamond is precisely that it is too expensive. It's supposed to be proof that I am glad to make sacrifices for her. If we wanted to do something nontraditional we might choose some completely different kind of ring, but to choose something that looks super expensive and is not would make me feel like I had cut corners for my fiance.

Why does she need this proof?

Why is wasting a ton of money proof of anything but stupidity?

Genuine questions here. Diamonds are certainly a feature of UK marriages but I've certainly never heard of "X months salary"...

You can make that sacrifice is more productive ways. You could give to charity, for example. Or use it for future financial security, like a deposit for your first house, kids' college fund, or something like that.
