Polished surface texture is a reflection of polished crystals that bring out the brilliant colors and grains of natural stones. The shine on stone surface comes from polishing bricks and powders used during fabrication and not from any coating. Polishing can be done only on crystallized stones and doesn't affect the porosity of the stone. Polished finish is quite popular as it enhances the colour and markings of the material. A stone with a polished finish is very smooth and reflective.
