Ashes to diamond

Did you know it's possible to compress the ashes (the carbon parts of them) from a dead body into a diamond? Neither did I. Not only that, it's done commercially.

Personally I don't feel that any of what's worthwhile in a person resides in the body, so when it's dead, I say let it go and begone with it. Scattering the ashes seems perfect. But the diamond thing is at least less morbid and wasteful than keeping the whole body around in a preserved state.
