Uranus and Neptune May Have "Oceans of Diamonds"

Third Position writes "Oceans of liquid diamond topped with solid 'icebergs' of the precious gems could be on Uranus and Neptune. The first-ever detailed research into the melting point of diamond found it behaves like water during melting and freezing — with its solid form floating on the liquid. A large diamond ocean on one or both of the planets could provide an explanation for an oddity they both share: unlike Earth, they do not have magnetic poles that match up with their geographical poles." The article doesn't mention what the pressures might be like in these outer-planets environments, but the researchers found that liquefying diamond requires 40 million times Earth's atmospheric pressure at sea level.

can't you just make a diamond in the lab?

Correct me if I'm wrong, but isn't the whole diamond market a big scam? Can't you make diamonds in a laboratory with elemental carbon at a fraction of the cost of what the diamond cartels charge?
