Only them rocks what will take a polish get given a polish. Polishing is hard work, so it only gets done on those rocks that can take it. Soft rocks like limestone and sandstone and brownstone (technically a sandstone I think) won't take a polish. Schist is hard enough, but has some schisty (I mean sh**ty) minerals that are soft, so it would come up all blotchy. Technically, the polish on rocks is achieved by grinding the rock to a very smooth surface. The 'softer' rocks have a high porosity, so that even if the minerals will accept the polish, the surface is disrupted by all the voids. I've seen polished sandstone - looks okay, but it doesn't have that wonderful mirror-reflection characteristic that we associate with a polished granite or marble. And as for limestone - most of the polished marbles you have seen are geologically speaking limestones, so you have seen polished limestone and just didn't know it! Marble like Carrara is real marble. Marble like the patterned reds and greens is actually hard or dense limestone (or maybe serpentine or some other sort of rock!). Have I confused you yet?
