The majority of granites are polished giving a shiny mirror-like finish that intensifies the color and enhances the pattern of the stone. Polishing reduces the porosity of the granite & increases resistance to humidity and chemical substances commonly found in the kitchen.
A few granites are available in a honed finish producing a smooth, non-reflective surface. This finish creates a more porous surface and should not be considered for a countertop that will be getting heavy use.
The brushed finish gives a textured satin smooth look.
