Diamonds are forever.

... Like, literally.

My dad was just telling me over lunch that, you can turn human ashes into diamonds using high pressure and temperature. 600g can produce 1 carat, I think. Or less than that. Can't remember la. And, they last forever.

It costs about 16,000 Euros (I think) to do that.

A bit eerie, right?

But then if you really want to, Ehow has a page telling you how to make your own. But obviously you can't because you don't have the kind of equipment!
