This looks like a sedimentary type of stone, have you tested to see if acid reacts to the stone. does the stone feel sandy or gritty ? from the pictures I would say no it may not polish. try to polish a small area to see what the stone does. My guess from these pictures, it not going to polish.

Yesterday I went to look at a stone floor and I don't know what it is? Can any of you identify this stone?Also, the owner wants to polish the stone. Will it take a polish? Please see attached photos.
