Dear Dave:
And if it is black “granite” why should it be dull?... It takes some serious, serious,
serious
doing to dull the surface of black “granite”!
That said, and assuming that it is indeed black “granite”, there are probably no more than a couple of dozen professional stone refinishers in the whole country that could pull a job like that off. Without meaning to dwarf your DIY abilities, somehow I doubt that you're among those few!...

Stone is polished mechanically by abrasion and friction, like gemstone, with special equipment, appropriate abrasives and polishing powders. The real difficult part is that no two stones polish the same way (it is never a standard procedure), and black “granite” is among the most difficult to do.
Sorry…

Ciao and good luck,
