why is high pressure needed to make diamonds in terms of equilibrium and that diamond has a higher density than graphite

Diamond has a giant covalent structure. One carbon atom is bonded to 4 other carbon atoms wheres graphite has a overlapping hexagonal ring therefore graphite is less dense than diamond.

thank you but. I mean for example
graphite=====>diamond ∆H=1.9Kjmol-1
suggest why a high temp and pressure are needed to convert graphite into diamond
(I get the temperature part) but in the markscheme it's written high pressure favors formation of higher density diamond and that higher pressure as same mass of diamond has smaller volume
