The same as liquid graphite. If I recall correctly, under high temperatures and pressures, carbon changes to graphite (which is a higher entropy structure) before any other physical change can occur.

No one knows for sure, because no one has really done it yet. But there are computer models.

Liquid diamond and carbon spaghetti : [http://www.nature.com/nsu/990617/990617-10.html](http://www.nature.com/nsu/990617/990617-10.html)

> The high-density form of liquid carbon is like a jumbled-up diamond – most of the atoms have four neighbours, but they are not arranged regularly as they are in diamond. The low-density form, meanwhile, is not like graphite at all, but contains mostly carbon atoms linked to just two others in chain-like structures: a kind of carbon spaghetti.
