So, if you didn’t already know, The DeBeers Company pretty much controls both supply and demand of diamonds to artificially inflate prices. And, they have nothing to do with beer. An article from The Straight Dope clears things up. Also, the next big threat is artificial diamonds, which are pretty much indistinguishable from the real thing, except they’re a little too perfect. Wired has a big article about that.
So, if you’re trying to get out of spending a fortune for a diamond ring, you have a lot of evidence that supporting the diamond industry is akin to supporting African poverty and blood feuds. And if that fails, you should soon be able to by a cheap, flawless diamond. Spend the rest on something the whole family can use, like gambling.
