I don't have problem with the cost so much (but serious proposals were supposed to be 3x the salary, no? so you lose quite a bit) but rather overall business and how it manipulates people. From poor people destroying their lives in Congo open pit mines to deBeers laughing in your face when selling you small rock which is not that rare for as much money as you are willing to accept. And if you got any form of certificate from then that your specific diamond is not blood diamond, well that paper has less value than used toilet paper, nobody could ever check or enforce that. So people here mentioning how their wives glow when looking at diamonds, well they are looking at shiny human suffering. And if future wife doesn't care enough about that, well you just learned a very interesting personality trait of her, without the need to go through years of relationship.
