can Tungsten dlc (matte) be polished

[MAXPOWER419]

can the matte finish of tungsten dlc, be made to look polished, like the old boron coating?

i know "hardmetal" which is tungstecarbide can be polished to look like a mirror, very beautiful indeed. this is done with diamonds. dont know if it will work on a coating or any non flat surface for that matter.
