Fieldstone Cobbles are a colorful natural granite thin stone veneer.  The raw stone boulders or mini boulders as they are sometimes called are not quarried but instead collected from glacial deposits.  The stone was deposited or dropped by the glacier as it moved south centuries ago.  The pieces of stone have a smooth tumbled feel; they are not tumbled by our machines but instead naturally tumbled by the glacier. As the glacier slowly moved, the stones turned and rubbed against each other.  This process changed the once jagged and irregular pieces of stone into the smooth round pieces we see today.  This granite is one of the hardest stones we cut in terms of compressive strength.
