Granite is one of the hardest stones available. It is extremely difficult to scratch, but it is not a diamond. Granite does not crack with ordinary use. Granite is most susceptible to cracks during fabrication, shipping and installation. Granite will not flex like laminate and solid surface tops. Do not stand on or next to the sink, cook top cutouts, or unsupported overhangs - as too much stress or weight applied to the stone may cause it to crack.
