Those De Beers commercials really blow my mind. Love is measured by the size of the rock you give to your loved one. If you can't afford it, take a loan, get a third mortgage on your house, sell your car. It's worth it, don't you see? Sell everything you own, go into debt so you can buy her the biggest damn engagement ring there was. If that's what she really wants, she'll probably leave you for the next schmuck with more money.
What's so great about diamonds anyway? They're very common. The only reason they cost so much is the company with the monopoly on the enormous South African diamond mines is controlling the output. They release only a small amount at a time because if the market actually got their greedy little paws on the whole stash, the resulting flood would cause diamond prices to drop faster than my Uncle's drawers when he loosens his belt after Christmas dinner.
The only reason diamonds are such a big attraction for the bourgeoisie is the price. They're expensive, so it must be the best. That's the philosophy. Hey, you know that stuff that's burned at barbecues? Charcoal, that's it. Guess what diamonds are made of? The very same. Carbon. Charcoal heated hotter than my neighbour's Szechwan cooking and squished harder than my Aunt's hugs equals diamonds. Believe it. So, save yourself some money and hassle. Buy her a charcoal engagement ring instead. She'll probably not be quite as pleased, but you'll still have a car to drive, a place to live and clothes to wear.
