this leads me to another thought. diamonds are made from carbon at high heat and pressure so then if a plaint has a high level of carbon with a higher amount of heat and pressure than Earth can we get a  carbon compound harder than diamond? Or is diamond as hard as carbon can get?

Hello allgoaway, at least by the indentation test there are some materials that appear to be harder than diamond: Harder than Diamond: Superior Indentation Strength of Wurtzite BN and Lonsdaleite

Sometimes very tiny diamonds and lonsdaleite crystals are found in a class of meteorites called ureilites. An unforgettable property to those that have cut slices of such meteorites with diamond saw blades, a very slow and difficult process. This study suggests a shock origin: Transformation of graphite to lonsdaleite and diamond in the Goalpara ureilite directly observed by TEM
