I know Vance hates those De Beers commercials, where a man showers his woman with major bling and gets everlasting love (or at least guaranteed nooky)in return.
Want to hate De Beers even more? Read this old article from the Atlantic Monthly about diamond cartels. Diamonds might be a girl's best friend but they're definitely a guy's worst enemy.
I kind of always wanted to know where that two-months-salary equation came from, but it's a little alarming to find out how the whole diamonds are forever thing became so pervasive. Subversive advertising--shudder.
