Idiots. Diamond is not intrinsically valuable; carbon is not rare, and industrial diamond is fairly cheap. Humans (and in particular one cartel) set a high value on gemstone diamonds.
It's going to be cheaper to turn waste carbon into diamond here on Earth than it is to boost any sort of mining platform out to another planet or our own asteroid belt, and this will continue to be true for many many years.
