Different concentrations of various minerals create the color variations and the relative porosity of all the different stones. Some granite countertops don’t really benefit from sealer in terms of their susceptibility to stains; after all it came out of the earth and if you like you could consider the various coloration of some stones to be “factory” designed stains!  When in doubt, always perform a test in an inconspicuous area or preferably on a sample of your exact stone.
